Book Synopsis Magnetoelectric Interaction Phenomena in Crystals by : Manfred Fiebig
Download or read book Magnetoelectric Interaction Phenomena in Crystals written by Manfred Fiebig and published by Springer Science & Business Media. This book was released on 2004-10-21 with total page 368 pages. Available in PDF, EPUB and Kindle. Book excerpt: In the quest for higher data density in information technology manipulation of magnetization by other means than magnetic fields has become an important challenge. This lead to a startling revival of the magnetoelectric effect, which characterizes induction of a polarization by a magnetic field or of a magnetization by an electric field. The magnetoelectric crosslink of material properties opens just those degrees of freedom which are needed for the mutual control of magnetic and electric states. The book gives a state-of-the-art review on magnetoelectrics research, classifies current research tendencies, and points out possible future trends. Novel compounds and growth techniques and new theoretical concepts for the understanding of magnetoelectric coupling phenomena are introduced. Highlights are the discovery of "gigantic" magnetoelectric effects which are strong enough to trigger electric or magnetic phase transitions; the concept of magnetochirality; and development "structural" magnetoelectric effects in artificial multiphase compounds. The book is addressed to condensed-matter physicists with a particular focus on experts in highly correlated systems.

Book Synopsis Neutron Capture Gamma-Ray Spectroscopy by : R. E. Chrien
Download or read book Neutron Capture Gamma-Ray Spectroscopy written by R. E. Chrien and published by Springer. This book was released on 2011-12-29 with total page 880 pages. Available in PDF, EPUB and Kindle. Book excerpt: The post World War II era witnessed a tremendous growth in the research carried out in neutron-induced reactions and especially in neutron capture y-ray studies. This growth was stimulated by the availability of neutron sources, such as reactors and accelerators, and by the development of high resolution y-ray and conversion electron detectors. Today the combination of high flux reactors and precise instrumentation has produced spectral data of exceptional quality, as the pages of these proceedings illustrate. The world-wide community of the practioners of the art of cap ture y-ray spectroscopy has met three times in the last decade: the first international symposium on this subject was held at Studsvik, Sweden in 1969, and the second at Petten, The Netherlands in 1974. A smaller meeting, of mostly u. S. and some European parti cipation, was held at Argonne National Laboratory in 1966. A perusal of the proceedings of these meetings shows the striking ad vances in this now mature field of physics over the last dozen years. Each meeting has seen a small but perceptible increase in the number of papers presented and the number of laboratories repre sented. More importantly, each meeting has documented the increasing impact of (n,y) reasearch, not only on other areas of basic physics, but also on commercial and medical applications of this technology. A total of 29 invited papers and 97 contributed papers were presented at this symposium.
Book Synopsis Dynamics of Disordered Materials by : Dieter Richter
Download or read book Dynamics of Disordered Materials written by Dieter Richter and published by Springer. This book was released on 1989 with total page 344 pages. Available in PDF, EPUB and Kindle. Book excerpt: This book contains the proceedings of a workshop held at the Institute Laue-Langevin in Grenoble in September 1988. Review articles and contributed papers survey recent theoretical and experimental developments on disordered materials and in particular on glasses. A large part of the book concerns the recently proposed mode-coupling approach to the behaviour of a viscous liquid around its glass transition, where the relevant dynamics extend over a broad range in time scales and the application of quite different experimental techniques becomes essential. Contributions report on experiments using dielectric relaxation, NMR or light scattering techniques, and especially neutron scattering techniques. One signature of disordered materials is the occurrence of an excess vibrational density of states at low frequencies. Some situations are presented where the density of states can be understood by taking into account the peculiarities of intra- and intermolecular motions. Another approach to the dynamics of disordered materials is the fracton picture, developed to describe the excitations of fractal objects. Several contributions discuss the dynamics of such fractals, studying mainly the vibrational density of states, and some discuss the application of the fracton concept to materials without a fractal structure like glasses.

Book Synopsis Elastic and Inelastic Scattering in Electron Diffraction and Imaging by : Zhong-lin Wang
Download or read book Elastic and Inelastic Scattering in Electron Diffraction and Imaging written by Zhong-lin Wang and published by Springer Science & Business Media. This book was released on 2013-06-29 with total page 461 pages. Available in PDF, EPUB and Kindle. Book excerpt: Elastic and inelastic scattering in transmission electron microscopy (TEM) are important research subjects. For a long time, I have wished to systematically summarize various dynamic theories associated with quantitative electron micros copy and their applications in simulations of electron diffraction patterns and images. This wish now becomes reality. The aim of this book is to explore the physics in electron diffraction and imaging and related applications for materials characterizations. Particular emphasis is placed on diffraction and imaging of inelastically scattered electrons, which, I believe, have not been discussed exten sively in existing books. This book assumes that readers have some preknowledge of electron microscopy, electron diffraction, and quantum mechanics. I anticipate that this book will be a guide to approaching phenomena observed in electron microscopy from the prospects of diffraction physics. The SI units are employed throughout the book except for angstrom (A), which is used occasionally for convenience. To reduce the number of symbols used, the Fourier transform of a real-space function P'(r), for example, is denoted by the same symbol P'(u) in reciprocal space except that r is replaced by u. Upper and lower limits of an integral in the book are (-co, co) unless otherwise specified. The (-co, co) integral limits are usually omitted in a mathematical expression for simplification. I very much appreciate opportunity of working with Drs. J. M. Cowley and J. C. H. Spence (Arizona State University), J.

Book Synopsis Electron Density and Bonding in Crystals by : V.G Tsirelson
Download or read book Electron Density and Bonding in Crystals written by V.G Tsirelson and published by CRC Press. This book was released on 2020-11-26 with total page 534 pages. Available in PDF, EPUB and Kindle. Book excerpt: Electron Density and Bonding in Crystals: Principles, Theory and X-Ray Diffraction Experiments in Solid State Physics and Chemistry provides a comprehensive, unified account of the use of diffraction techniques to determine the distribution of electrons in crystals. The book discusses theoretical and practical techniques, the application of electron density studies to chemical bonding, and the determination of the physical properties of condensed matter. The book features the authors' own key contributions to the subject as well a thorough, critical summary of the extensive literature on electron density and bonding. Logically organized, coverage ranges from the theoretical and experimental basis of electron density determination to its impact on investigations of the nature of the chemical bond and its uses in determining electromagnetic and optical properties of crystals. The main text is supplemented by appendices that provide clear, concise guidance on aspects such as systems of units, quantum theory of atomic vibrations, atomic orbitals, and creation and annihilation operators. The result is a valuable compendium of modern knowledge on electron density distributions, making this reference a standard for crystallographers, condensed matter physicists, theoretical chemists, and materials scientists.
Book Synopsis Electron Crystallography by : D. Dorset
Download or read book Electron Crystallography written by D. Dorset and published by Springer Science & Business Media. This book was released on 2013-04-17 with total page 447 pages. Available in PDF, EPUB and Kindle. Book excerpt: The re-emergent field of quantitative electron crystallography is described by some of its most eminent practitioners. They describe the theoretical framework for electron scattering, specimen preparation, experimental techniques for optimum data collection, the methodology of structure analysis and refinement, and a range of applications to inorganic materials (including minerals), linear polymers, small organic molecules (including those used in nonlinear optical devices), incommensurately modulated structures (including superconductors), alloys, and integral membrane proteins. The connection between electron crystallography and X-ray crystallography is clearly defined, especially in the utilisation of the latest methods for direct determination of crystallographic phases, as well as the unique role of image analysis of high-resolution electron micrographs for phase determination. Even the aspect of multiple beam dynamic diffraction (once dreaded because it was thought to preclude ab initio analysis) is considered as a beneficial aid for symmetry determination as well as the elucidation of crystallographic phases, and as a criterion for monitoring the progress of structure refinement. Whereas other texts have hitherto preferentially dealt with the analysis of electron diffraction and image data from thin organic materials, this work discusses - with considerable optimism - the prospects of looking at `harder' materials, composed of heavier atoms. Audience: Could be used with profit as a graduate-level course on electron crystallography. Researchers in the area will find a statement of current progress in the field.
Book Synopsis Many-beam Electron Diffraction Related to Electron Microscope Diffraction Contrast by : Gerhard Kästner
Download or read book Many-beam Electron Diffraction Related to Electron Microscope Diffraction Contrast written by Gerhard Kästner and published by De Gruyter Akademie Forschung. This book was released on 1993 with total page 116 pages. Available in PDF, EPUB and Kindle. Book excerpt: The present work is to serve as a theoretical and practical guide for exploiting these possibilities. It comprehensively reviews the required dynamical and kinematical diffraction theory thus closing some gaps, e. g. by systematically comparing "ordinary" and "modified" Bloch waves, or by denoting conditions of a first-order critical voltage effect. It is shown how to classify and simplify many-beam situations and imaging conditions.
Book Synopsis High Energy Electron Diffraction and Microscopy by : L. M. Peng
Download or read book High Energy Electron Diffraction and Microscopy written by L. M. Peng and published by Oxford University Press. This book was released on 2004-01-08 with total page 558 pages. Available in PDF, EPUB and Kindle. Book excerpt: This book provides a comprehensive introduction to high energy electron diffraction and elastic and inelastic scattering of high energy electrons, with particular emphasis on applications to modern electron microscopy. Starting from a survey of fundamental phenomena, the authors introduce the most important concepts underlying modern understanding of high energy electron diffraction. Dynamical diffraction in transmission (THEED) and reflection (RHEED) geometries is treated using a general matrix theory, where computer programs and worked examples are provided to illustrate the concepts and to familiarize the reader with practical applications. Diffuse and inelastic scattering and coherence effects are treated comprehensively both as a perturbation of elastic scattering and within the general multiple scattering quantum mechanical framework of the density matrix method. Among the highlights are the treatment of resonance diffraction of electrons, HOLZ diffraction, the formation of Kikuchi bands and lines and ring patterns, and application of diffraction to monitoring of growing surfaces. Useful practical data are summarised in tables including those of electron scattering factors for all the neutral atoms and many ions, and the temperature dependent Debye-Waller factors given for over 100 elemental crystals and compounds.
Book Synopsis Crystal-Quasicrystal Transitions by : M.J. Yacamán
Download or read book Crystal-Quasicrystal Transitions written by M.J. Yacamán and published by Elsevier. This book was released on 1993-03-18 with total page 248 pages. Available in PDF, EPUB and Kindle. Book excerpt: The discovery of five-fold diffraction symmetry by D. Schechtman in 1985 shocked crystallography to its roots. Incommensurable modulation of a crystal changes former identical unit cells into different ones. This radical revolution has given rise to the study of an entirely new class of matter, the quasicrystalline materials. The study of these quasi-periodic crystals brings a unique elucidation of the fundaments of crystallography and the relationship between lattice structure and macroscopic properties. This book covers the transitions between the crystalline and the quasicrystalline state. A thorough understanding of the transition from quasiperiodic to periodic lattices is essential in order to investigate the uniqueness of quasicrystals. In this well-written volume, an overview is given of the most important problems in quasicrystallography today. Leading experts provide insight into recent experimental advances achieved by studying the phase transitions between crystalline and quasicrystalline states. In the theoretical chapters one is introduced to the depth of insight into the nature of crystallography which has arisen through a rigorous understanding of the quasicrystal structure. This book is an essential source of reference for crystallographers, crystal growers and solid state physicists working in the field.
Book Synopsis Large-Angle Convergent-Beam Electron Diffraction Applications to Crystal Defects by : Jean- Paul Morniroli
Download or read book Large-Angle Convergent-Beam Electron Diffraction Applications to Crystal Defects written by Jean- Paul Morniroli and published by CRC Press. This book was released on 2004-11-01 with total page 432 pages. Available in PDF, EPUB and Kindle. Book excerpt: A publication of the French Society of Microscopies, Large-Angle Convergent-Beam Electron Diffraction Applications to Crystal Defects is devoted to an important aspect of electron diffraction. Convergent-beam diffraction is capable of furnishing remarkably accurate crystallographic information. In this book, the author goes well beyond a simple presentation of the method. The description of convergent-beam electron diffraction and especially of LACBED is preceded by several preparatory chapters, in which the principles of diffraction and the nature of electron-matter interactions are clearly set out. An entire chapter is concerned with instrumentation. Another on the interpretation of diffraction patterns enables the reader to master all stages in the process. The book ends with a long chapter in which numerous applications concerned with the characterization of crystal defects are examined and analyzed.
