Book Synopsis Relaxation in Magnetic Resonance by : Charles P. Jr. Poole
Download or read book Relaxation in Magnetic Resonance written by Charles P. Jr. Poole and published by Elsevier. This book was released on 2012-12-02 with total page 409 pages. Available in PDF, EPUB and Kindle. Book excerpt: Relaxation in Magnetic Resonance contains a series of lecture notes for a special topics course at the University of South Carolina in 1967. This book contains 21 chapters that summarize the main theoretical formulations and experimental results of magnetic resonance relaxation phenomena in several physical systems. This text deals first with the various methods in determining the relaxation behavior of the macroscopic spin system, such as Bloch equations, saturation methods, and transient resonant absorption. The subsequent chapters discuss the homogeneous and inhomogeneous resonant lines in solids and liquids and the significance of the Kubo-Tomita and Redfield theories in magnetic resonance. This book then considers the background research on electron spin resonance and relaxation in ionic solids. The concluding chapters explore the acoustic absorption coefficient and dielectric constant calculation; the relaxation processes in paramagnetic substance; and the characteristics of Mössbauer spectra and their application in magnetic relaxation. This book will be useful to both graduate students embarking upon thesis problems in relaxation and more advanced workers who seek an overall summary of the status of the field, as well as to physicists and chemists.

Book Synopsis Magnetic Resonance by : C. K. Coogan
Download or read book Magnetic Resonance written by C. K. Coogan and published by Springer Science & Business Media. This book was released on 2012-12-06 with total page 388 pages. Available in PDF, EPUB and Kindle. Book excerpt: TWENTY-FIVE years ago in Russia, Zavoisky made the first experimen tal observation of electron spin resonances; and a year later Purcell, Torrey and Pound at Harvard and Bloch, Hansen and Packard at Stanford ('The Harvard of the West') observed nuclear magnetic resonances for the first time. In both cases (ESR and NMR) the phenomena had been previously predicted, and Gorter - surely one of the most unlucky experimenters of our time - had made his noble attempts to detect magnetic resonances. Purcell et aZ. , having beaten their radar swords into scientific ploughshares, used a re 3 sonant coaxial cavity, filled the inductive part with 850 cm of paraffin, and produced a resonance with a signal-to-noise ratio of 20. They predicted that the sensitivity could be increased several hundred-fold and foresaw applications in determining magnetic mo ments, investigating spin-lattice coupling and measuring magnetic fields. Their letter reached the editor of Phys. Rev. on Christmas Eve 1945, and the basis of NMR in the solid state was laid. Bloch et aZ. , fortunately working independently, established the entirely different, crossed-coil approach to the observation of NMR in a water sample, which they doped with paramagnetic ions to reduce the relaxation times. They had laid the foundation of liquid-state NMR. Their letter to Phys. Rev. was received on 29 January 1946.

Available in PDF, EPUB and Kindle. Book excerpt: Advances in Magnetic Resonance, Volume 2, features a mixture of experimental and theoretical contributions. The book contains four chapters and begins with an ambitious and general treatment of the problem of signal-to-noise ratio in magnetic resonance. This is followed by separate chapters on the interpretation of nuclear relaxation in fluids, with special reference to hydrogen; and various aspects of molecular theory of importance in NMR.
Book Synopsis Principles of Magnetic Resonance by : Charles P. Slichter
Download or read book Principles of Magnetic Resonance written by Charles P. Slichter and published by Springer. This book was released on 2013-01-22 with total page 658 pages. Available in PDF, EPUB and Kindle. Book excerpt: The first edition of this book was written in 1961 when I was Morris Loeb Lecturer in Physics at Harvard. In the preface I wrote: "The problem faced by a beginner today is enormous. If he attempts to read a current article, he often finds that the first paragraph refers to an earlier paper on which the whole article is based, and with which the author naturally assumes familiarity. That reference in turn is based on another, so the hapless student finds himself in a seemingly endless retreat. I have felt that graduate students or others beginning research in magnetic resonance needed a book which really went into the details of calculations, yet was aimed at the beginner rather than the expert. " The original goal was to treat only those topics that are essential to an understanding of the literature. Thus the goal was to be selective rather than comprehensive. With the passage of time, important new concepts were becoming so all-pervasive that I felt the need to add them. That led to the second edition, which Dr. Lotsch, Physics Editor of Springer-Verlag, encouraged me to write and which helped launch the Springer Series in Solid-State Sciences. Now, ten years later, that book (and its 1980 revised printing) is no longer available. Meanwhile, workers in magnetic resonance have continued to develop startling new insights.

Book Synopsis Introduction to Frustrated Magnetism by : Claudine Lacroix
Download or read book Introduction to Frustrated Magnetism written by Claudine Lacroix and published by Springer Science & Business Media. This book was released on 2011-01-12 with total page 682 pages. Available in PDF, EPUB and Kindle. Book excerpt: The field of highly frustrated magnetism has developed considerably and expanded over the last 15 years. Issuing from canonical geometric frustration of interactions, it now extends over other aspects with many degrees of freedom such as magneto-elastic couplings, orbital degrees of freedom, dilution effects, and electron doping. Its is thus shown here that the concept of frustration impacts on many other fields in physics than magnetism. This book represents a state-of-the-art review aimed at a broad audience with tutorial chapters and more topical ones, encompassing solid-state chemistry, experimental and theoretical physics.

Book Synopsis The Theory of Magnetic Resonance by : Charles P. Poole
Download or read book The Theory of Magnetic Resonance written by Charles P. Poole and published by John Wiley & Sons. This book was released on 1972 with total page 496 pages. Available in PDF, EPUB and Kindle. Book excerpt: This second edition of the well-known work stresses important aspects of magnetic resonance theory that are of increasing importance to the research worker. Presents mathematical background and the basic prototype two-spin 1/2-1/2 Hamiltonian treatment as a building block to the more specialized subjects developed: higher spins and anistropies, applications to atomic spectra, crystal field theory, Mossbauer resonance, types of double resonance, and dynamic polarization. Specialized extensions are then discussed at length, with the advantage of showing clearly their relationships to the main body of magnetic resonance theory: ENDOR, ELDOR, polarization, spin labels, saturation transfer and fourier transform methods, and NMR imaging. Much of this material is treated by means of the uniform formalism based on the direct product matrix expansion technique.
Book Synopsis Electron Paramagnetic Resonance Studies of Symmetry Enforced Quantum Tunneling in Molecule-Based Magnets by : Junjie Liu
Download or read book Electron Paramagnetic Resonance Studies of Symmetry Enforced Quantum Tunneling in Molecule-Based Magnets written by Junjie Liu and published by . This book was released on 2012 with total page 173 pages. Available in PDF, EPUB and Kindle. Book excerpt: This dissertation presents studies of several molecule-based magnets using both experimental and theoretical methods to understand the quantum tunneling and thermally assisted magnetic relaxation at the single-ion level. The molecule-based magnets presented in this dissertation can be sorted into two categories: a) single-molecule magnets (SMMs) and b) single-chain magnets (SCMs). In these systems, the quantum tunneling and thermally assisted magnetic relaxation play critical roles both in terms of fundamental scientific reasons and due to the potential applications of SMMs and SCMs in information technologies. Electron paramagnetic resonance (EPR) and quantum tunneling of magnetization (QTM) were employed as two spectroscopic techniques to probe the rich physics of these magnetic materials. Detailed EPR measurements were performed on two dinuclear [MnIII]2 molecular magnets to study the interplay between magnetic anisotropy and exchange interactions. These results show the importance of considering both interactions in interpreting magnetometry measurements performed at both high and low temperatures.
