Book Synopsis Characterisation of Soft Magnetic Materials Under Rotational Magnetisation by : Stanislaw Zurek
Download or read book Characterisation of Soft Magnetic Materials Under Rotational Magnetisation written by Stanislaw Zurek and published by CRC Press. This book was released on 2017-11-22 with total page 568 pages. Available in PDF, EPUB and Kindle. Book excerpt: The book presents practical aspects related to the measurement of rotational power loss in soft magnetic materials. The book furthermore focuses on practical aspects of performing such measurements, the associated difficulties as well as solutions to the most common problems. Numerous practical aspects, hands-on experience, and most commonly encountered pitfalls are heavily discussed in the book. The text begins with introduction to magnetism, then follows with definitions of measurement methods of rotational power loss from physical viewpoint. Two chapters describe and detail the various sensors which can be employed for such measurements as well as all the aspects of designing, making, and using a magnetising apparatus. A synthesis of the likely optimal design of a magnetising apparatus is also given, preceded with the full reasoning based on all the research carried out to date. Characterisation of Soft Magnetic Materials Under Rotational Magnetisation serves as an excellent starting point for any student having to perform magnetic measurements under rotational magnetisation, but also under 1D, 2D or 3D excitation. Because the methods, sensors, and apparatus are extensively discussed it will also be a great reference for more senior researchers and experts in the field. There is a whole chapter devoted to analysis of measurement uncertainty. This subject is rarely published for magnetic measurements, which makes it more difficult for all researchers to understand the concepts and methodology used in uncertainty estimation. This chapter not only introduces the whole subject, but also provides multiple step-by-step examples which can be easily followed, from very simple cases to much more complex ones. All equations are presented with full SI units which greatly helps in practical application of the presented methodology. Each chapter is written in such a way that it can be studied on its own, so that the reader can focus only on the specific aspects, as required.
Book Synopsis Phase Transitions and Magnetocaloric Effect in MnNiGe 1--xAlx, Ni50Mn35(In1--x Crx)15 and (Mn1--xCrx)NiGe 1.05 by : Abdiel Quetz
Download or read book Phase Transitions and Magnetocaloric Effect in MnNiGe 1--xAlx, Ni50Mn35(In1--x Crx)15 and (Mn1--xCrx)NiGe 1.05 written by Abdiel Quetz and published by . This book was released on 2014 with total page 168 pages. Available in PDF, EPUB and Kindle. Book excerpt: The magnetocaloric and thermomagnetic properties of the MnNiGe1-x Alx , Ni50 Mn35 (In1-x Cr x )15 and (Mn1-x Crx )NiGe 1.05 systems have been studied by x-ray diffraction, differential scanning calorimetry (DSC), and magnetization measurements. Partial substitution of Al for Ge in MnNiGe1-x Al x results in a first-order magnetostructural transition (MST) from a hexagonal ferromagnetic to an orthorhombic antiferromagnetic phase at 186 K (for x = 0.09). The concentration-dependent (T-x) phase diagram of transition temperatures (magnetic, structural, and magnetostructural) has been generated using magnetic, XRD, and DSC data. The role of magnetic and structural changes on transition temperatures are discussed.
Book Synopsis The Magnetocaloric and Elastocaloric Effects in Magnetic Shape Memory Alloys by : Nickolaus Mark Bruno
Download or read book The Magnetocaloric and Elastocaloric Effects in Magnetic Shape Memory Alloys written by Nickolaus Mark Bruno and published by . This book was released on 2015 with total page pages. Available in PDF, EPUB and Kindle. Book excerpt: The present work focuses on the microstructural and magneto-thermo-mechanical characterization of off-stoichiometric meta-magnetic shape memory alloys (MMSMAs) with the aim of identifying key material parameters to optimize their giant magneto- (MCE) and elastocaloric (ECE) effects. Several alloy compositions of NiFeGa, Ni(Co)MnIn, and Ni(Co)MnSn have been studied to quantify their solid state energy conversion performance, in particular the conversion of magnetic and mechanical energy into thermal energy, and to reveal how this performance is influenced by microstructural features tailored using carefully selected heat treatments. To identify how heat treatments influence the energy conversion performance of the selected alloys, a previously established thermodynamic framework, which defines the refrigerant capacity (RC) of non-shape memory alloys (SMAs), was employed with the thermodynamic relations describing first order martensitic phase transitions. Applying the RC framework to MMSMAs demonstrated that most of the key materials parameters relating to the martensitic transition can be combined to predict the magnetic field, or mechanical stress, needed to complete the transformation across a specific operating temperature range; reducing these driving force requirements was the primary focus of the experimental part of this work. Magnetometry, calorimetry, and specialized compression tests were performed on the heat treated SMAs. An experimental apparatus, called the magneto-thermo-mechanical characterization (MaTMeCh) device, was designed, constructed, and implemented to reduce the magnetic field requirements needed for a complete field-induced martensitic transformation by simultaneous application of external stress and magnetic field. This device allows simultaneous control of temperature, magnetic field, and stress while measuring magnetization, strain, stress, and temperature. With the MaTMeCh device, uniaxial compressive stresses up to 200MPa, magnetic fields up to 9T, and temperatures between -100°C and 80°C can be applied to a compression specimen. Using the MaTMeCh device, cyclic stress-assisted magnetic field induced transitions demonstrated the full thermal energy conversion capabilities of cost effective meta-magnetic shape memory alloys. Prior to magneto-thermo-mechanical characterization, numerous SMA compositions were fabricated and heat treated to promote grain growth and a specific degree of long range crystallographic order. Studies, herein, indicated that minimizing the microstructural grain constraint, by producing a large grain size to thickness (GS/t) ratio in polycrystalline SMA ribbons, ultimately reduced the magnetic field levels needed to completely harness the SMA's magnetocaloric effect. Additionally, B2 crystallographic ordering in NiCoMnIn single crystals was found to offer a more efficient magnetic to thermal energy conversion efficiency than the typical L21 ordered alloys. Larger caloric effects were measured in the alloys exhibiting a higher martensitic transformation temperature, i.e. the B2 ordered alloys. As such, B2 ordered single crystals were characterized with the MaTMeCh device, thus lending the ability to measure their maximal magnetocaloric performance.

Book Synopsis Magnetocaloric Energy Conversion by : Andrej Kitanovski
Download or read book Magnetocaloric Energy Conversion written by Andrej Kitanovski and published by Springer. This book was released on 2014-12-03 with total page 471 pages. Available in PDF, EPUB and Kindle. Book excerpt: This book provides the latest research on a new alternative form of technology, the magnetocaloric energy conversion. This area of research concerns magnetic refrigeration and cooling, magnetic heat pumping and magnetic power generation. The book’s systematic approach offers the theoretical basis of magnetocaloric energy conversion and its various sub domains and this is supported with the practical examples. Besides these fundamentals, the book also introduces potential solutions to engineering problems in magnetocalorics and to alternative technologies of solid state energy conversion. The aim of the book is therefore to provide engineers with the most up-to-date information and also to facilitate the understanding, design and construction of future magnetocaloric energy conversion devices. The magnetocaloric energy conversion represents an alternative to compressor based refrigerators and heat pumps. It is a serious alternative to power generation with low enthalpy heat sources. This green technology offers an opportunity to use environmentally friendly solid refrigerants and the potentially high energy efficiency follows the trends of future energy conversion devices. This book is intended for postgraduate students and researchers of refrigeration, heat pumping, power generation alternatives, heat regenerators and advanced heat transfer mechanisms.
Book Synopsis Magnetism and Structure in Functional Materials by : Antoni Planes
Download or read book Magnetism and Structure in Functional Materials written by Antoni Planes and published by Springer Science & Business Media. This book was released on 2010-02-11 with total page 261 pages. Available in PDF, EPUB and Kindle. Book excerpt: Magnetism and Structure in Functional Materials addresses three distinct but related topics: (i) magnetoelastic materials such as magnetic martensites and magnetic shape memory alloys, (ii) the magnetocaloric effect related to magnetostructural transitions, and (iii) colossal magnetoresistance (CMR) and related manganites. The goal is to identify common underlying principles in these classes of materials that are relevant for optimizing various functionalities. The emergence of apparently different magnetic/structural phenomena in disparate classes of materials clearly points to a need for common concepts in order to achieve a broader understanding of the interplay between magnetism and structure in this general class of new functional materials exhibiting ever more complex microstructure and function. The topic is interdisciplinary in nature and the contributors correspondingly include physicists, materials scientists and engineers. Likewise the book will appeal to scientists from all these areas.

Book Synopsis Disorder and Strain-Induced Complexity in Functional Materials by : Tomoyuki Kakeshita
Download or read book Disorder and Strain-Induced Complexity in Functional Materials written by Tomoyuki Kakeshita and published by Springer Science & Business Media. This book was released on 2011-10-27 with total page 316 pages. Available in PDF, EPUB and Kindle. Book excerpt: This book brings together an emerging consensus on our understanding of the complex functional materials including ferroics, perovskites, multiferroics, CMR and high-temperature superconductors. The common theme is the existence of many competing ground states and frustration as a collusion of spin, charge, orbital and lattice degrees of freedom in the presence of disorder and (both dipolar and elastic) long-range forces. An important consequence of the complex unit cell and the competing interactions is that the emergent materials properties are very sensitive to external fields thus rendering these materials with highly desirable, technologically important applications enabled by cross-response.

Available in PDF, EPUB and Kindle. Book excerpt: The present book is the second edition of Amikam Aharoni's Introduction to the Theory of Ferromagnetism, based on a popular lecture course. Like its predecessor, it serves a two-fold purpose: First, it is a textbook for first-year graduate and advanced undergraduate students in both physics and engineering. Second, it explains the basic theoretical principles on which the work is based for practising engineers and experimental physicists who work in the field of magnetism, thus also serving to a certain extent as a reference book. For both professionals and students the emphasis is on introducing the foundations of the different subfields, highlighting the direction and tendency of the most recent research. For this new edition, the author has thoroughly updated the material especially of chapters 9 ('The Nucleation Problem') and 11 ('Numerical Micromagnetics'), which now contain the state of the art required by students and professionals who work on advanced topics of ferromagnetism. From reviews on the 1/e: '... a much needed, thorough introduction and guide to the literature. It is full of wisdom and commentary. Even more, it is Amikam Aharoni at his best - telling a story... He is fun to read... The extensive references provide an advanced review of micromagnetics and supply sources for suitable exercises... there is much for the student to do with the guidance provided by Introduction to the Theory of Ferromagnetism.'

Book Synopsis Handbook of Magnetic Materials by : K.H.J. Buschow
Download or read book Handbook of Magnetic Materials written by K.H.J. Buschow and published by Gulf Professional Publishing. This book was released on 2001 with total page 606 pages. Available in PDF, EPUB and Kindle. Book excerpt: Volume 13 of the Handbook of Magnetic Materials, as the preceding volumes, has a dual purpose. As a textbook it is intended to be of assistance to those who wish to be introduced to a given topic in the field of magnetism without the need to read the vast amount of literature published. As a work of reference it is intended for scientists active in magnetism research. To this dual purpose, Volume 13 of the Handbook is composed of topical review articles written by leading authorities. In each of these articles an extensive description is given in graphical as well as in tabular form, much emphasis being placed on the discussion of the experimental material in the framework of physics, chemistry and material science. In Chapter 1 of this volume a general review of the experimental work on interlayer exchange coupling is presented along with a discussion of the current understanding of this field. There exists an extensive amount of scientific efforts devoted to 4f and 5f systems, including experimental and theoretical, as well as basic and applied research. Chapter 2 aims at reviewing a part of these efforts from the viewpoint of microscopic theory. Special attention is paid to the many new developments in the field. One of the intentions is to bring to the fore the darker areas of DFT theory applications. A review of novel experimental results and first-principle energy-band calculations of MOKE spectra will be presented in Chapter 3. Conventional co-operative phenomena, such as long-range order and elementary excitation, have realisations in nonmagnetic situations. This applies also to the phenomena of geometrical frustration. In Chapter 4 this topic is addressed by developing the basic principles underlying the magnetic phenomena.
