Book Description
An understanding of the quantum mechanical nature of magnetism has led to the development of new magnetic materials which are used as permanent magnets, sensors, and in information storage. Behind these practical applications lie a range of fundamental ideas, including symmetry breaking, order parameters, excitations, frustration, and reduced dimensionality.This superb new textbook presents a logical account of these ideas, starting from basic concepts in electromagnetism and quantum mechanics. It outlines the origin of magnetic moments in atoms and how these moments can be affected by their local environment inside a crystal. The different types of interactions which can be present between magnetic moments are described. The final chapters of the book are devoted to the magnetic properties of metals, and to the complex behaviour which can occur when competing magnetic interactions are present and/or the system has a reduced dimensionality.Throughout the text, the theoretical principles are applied to real systems. There is substantial discussion of experimental techniques and current research topics.The book is copiously illustrated and contains detailed appendices which cover the fundamental principles ...

Good overview of magnetism
This book is an easy to read overview of the subject. It's a good book to review the fundamentals (para/dia/ferro/anti magnetism,
exchange interaction, etc.). I gave it 4 stars instead of 5 because the price is a bit high, and sometimes the treatments lacks depth. ... Read more

Book Description
This book presents a phenomenological approach to the field of solid state magnetism. After introducing the basic concepts from statistical thermodynamics and electronic structure theory, the first part discusses the standard models for localized moments (Weiss, Heisenberg) and delocalized moments (Stoner). This is followed by a chapter about exchange and correlation in metals, again considering the results for the localized and delocalized limit. The book ends with a chapter about spin fluctuations, which are introduced as an alternative to the finite temperature Stoner theory. The book will be a useful reference for researchers and a valuable accompaniment to graduate courses on magnetism and magnetic materials. ... Read more

Book Description
This monograph presents a unified and coherent account of an important, focused area of rare-earth magnetism -- magnetic structures and excitations -- which both reflects the nature of the fundamental magnetic interactions and determines many of the characteristic properties of metals. The
authors concentrate on the essential principles and their applications to typical examples, generally restricting the discussion to the pure elements and considering alloys and compounds only when they are instructive in illuminating particular topics. Both authors have been involved for some time
in the effort that has been made in Denmark to study, both theoretically and experimentally, the magnetic structures and especially the excitations in the rare earths. This account of the subject represents the result of their experience, and it has been written in the hope that it will be useful
not only to those who have a special interest in rare-earth magnetism, but also to a wider audience of physicists and condensed matter scientists interested in the techniques and achievements of modern research in magnetism. ... Read more

Book Description
Rock Magnetism is a comprehensive treatment of fine particle magnetism and the magnetic properties of rocks. Starting from atomic magnetism and magnetostatic principles, the authors explain why domains and micromagnetic structures form in ferromagnetic crystals and how these lead to magnetic memory in the form of thermal, chemical and other remanent magnetizations. The phenomenal stability of these magnetizations, providing a record of plate tectonic motions over millions of years, is explained by thermal activation theory. One chapter is devoted to practical tests of domain state and paleomagnetic stability; another deals with pseudo-single-domain magnetism. The final four chapters place magnetism in the context of igneous, sedimentary, metamorphic, and extraterrestrial rocks. This book will be of great value to graduate students and researchers in geophysics and geology, particularly in paleomagnetism and rock magnetism, as well as physicists and electrical engineers interested in fine-particle magnetism and magnetic recording. ...

Excellent book!!!
This book is the best of its kind! Scientifically rigorous, easily understandable, exceptionally comprehensive and has much useful information.

It covers the basics of magnetism through to fine details of rock/soil magnetism. This subject is complex and it does take a book of its length of 600 pages to cover it. The book is well written and concise. It is possibly atypical of books of this nature in that it concentrates more on maths and the physics, rather than "environmental" aspects.

It does not include the geology of rock/soil formation etc, nor related subjects such as ferrofluids, industrial ferrites etc, nor measurement techniques. Rather, it sticks to the subject and for this reason is exceptionally comprehensive. ... Read more

Book Description
The fundamental physics of metallic magnetism is not yetsatisfactorily understood and continues to be interesting. Forinstance, magnetism is anticipated to play a principal role inproducing high T_c superconductivity of oxides.
This book has two major objectives. First, it intends to provide anintroduction to magnetism of metals in a broad sense. Besides pursuingthe mechanism of metallic magnetism itself, it attempts to find andactively analyze magnetic causes hidden hitherto unnoticed behindvarious physical phenomena.
The author's goal is to expose the fundamental role played by phononsin the mechanism of metallic magnetism. He demonstrates how such aview also helps to elucidate a broad spectrum of other observations.The second objective is to concisely introduce the standard many-bodypoints of view and techniques necessary in studying solid physics ingeneral. ...

Book Description
The aim of this book is to review recent achievements in the theoretical investigations of the electronic structure, optical, magneto-optical (MO), and x-ray magnetic circular dichroism (XMCD) properties of compounds and Multilayered structures.
Chapter 1 of this book is of an introductory character and presents the theoretical foundations of the band theory of solids such as the density functional theory for ground state properties of solids including local density approximation (LDA). It also presents some modifications to the LDA, such as gradient correction, self-interaction correction, LDA+U method, orbital polarization correction, GW approximation, and dynamical mean-field theory. The description of the magneto-optical effects and linear response theory are also presented.
The book describes the MO properties for a number of 3d materials, such as elemental ferromagnetic metals (Fe, Co and Ni) and paramagnetic metals in external magnetic fields (Pd and Pt), some important 3d compounds such as XPt3 (X=V, Cr, Mn, Fe and Co), Heusler alloys, chromium spinel chalcogenides, MnB and strongly correlated magnetite Fe304. It also describes the recent achievements in both the experimental and theoretical investigations of the electronic structure, optical and MO properties of transition metal multilayered structures (MLS).
The book also presents the MO properties of f band ferromagnetic materials: Tm, Nd, Sm, Ce and La monochalcogenides, some important Yb compounds, SmB6 and Nd3S4, UFe2, U3X4 (X=P, As, Sb, Bi, Se and Te), UCu2P2, UCuP2, UCuAs2, UAsSe, URhA1, UGa2 and UPd3. Within the total group of alloys and compounds, we discuss their MO spectra in relationship to: the spin-orbit coupling strength, the magnitude of the local magnetic moment, the degree of hybridization in the bonding, the half-metallic character, or, equivalently, the Fermi level filling of the bandstructure, the intraband plasma frequency, and the influence of the crystal structure.
In the last chapter results of recent theoretical investigations on the MXCD in various representative transition metal 4f and 5f systems are presented. ... Read more

Book Description
Molecular magnetism is a new field of research dealing with the synthesis and study of the physical properties of molecular assemblies involving open-shell units. It is essentially interdisciplinary, joining together organic, organometallic and inorganic chemists, as well as theoreticians, physicists and materials scientists.
At the core of research into molecular magnetism lie design and synthesis of new molecular assemblies exhibiting bulk properties such as long-range magnetic ordering or bistability with an hysteresis effect, which confers a memory effect on the system. In such terms, magnetism may be considered a supramolecular function.
The first eight contributions to this volume present the state of the art in organic supramolecular chemistry, emphasising interlocked systems and molecular trees. The following six articles are devoted to molecular materials constructed from organic radicals and transition metal units. Molecular bistability is then focused on, followed by metal-organic and coordination magnetic materials. A new approach to nano-sized particles closes the work. ... Read more
