This book was released on 2023-09-23 with total page 79 pages. Available in PDF, EPUB and Kindle. Book excerpt: This book is based on a course of lectures aimed at undergraduate and graduate students studying materials science and welding at the E.O. Paton Institute of Materials Science and Welding National Technical University of Ukraine "Igor Sikorsky Kyiv Polytechnic Institute." The book is divided into four parts, each focusing on various aspects of magnetic solitons in ferromagnetic nanosystems. The first two parts of the book cover the quantum and thermodynamic properties of uniaxial ferromagnetic films with strong magnetic anisotropy and cylindrical nanowires made of different chemical compositions (ferrite-garnet, iron, nickel). These properties are related to the presence of "kink" solitons, which are vertical Bloch lines (BLs) and domain walls (DWs) of transverse type, respectively. The third part of the book discusses the effect of thermal motion of transverse-type DWs on the magnetocaloric effect in cylindrical iron and nickel nanowires. The fourth part of the book explores the conditions that lead to structural transitions between different types of DWs, including transverse, asymmetric, and DWs with a Bloch point (point soliton). Each part of the book is summarized at the end, highlighting the main results presented. Overall, the book is designed to provide students with a comprehensive understanding of magnetic solitons in ferromagnetic nanosystems and their associated quantum, thermodynamic, and structural properties.

This book was released on 2010 with total page 890 pages. Available in PDF, EPUB and Kindle. Book excerpt: The synthesis and study of magnetic nanostructures is of both intense scientific and technological interest. A single-molecule magnet (SMM) is a molecular nanomagnet that can be magnetized as a result of having a large spin ground state that experiences appreciable magnetoanisotropy, which leads to a thermodynamic barrier between "spin-up" and "spin-down" orientations. The monodisperse nature (same size, shape and anisotropy) of SMMs permits detailed studies of the magnetization and quantum dynamics of nanomagnets. The discovery of SMMs permitted, for the first time, detailed study of quantum effects associated with nanomagnets. The magnetic and quantum properties of these complexes is heavily dictated by molecular and crystal symmetry, and paramount to employing these systems as devices is a need to thoroughly understand and control environmental factors that govern their magnetization and quantum dynamics. To some extent this can be achieved by changing or eliminating co-crystallized solvate molecules and interchanging coordinated peripheral ligands. Magnetic and thermodynamic studies were carried out on a high symmetry system that exhibits a large spin ground state (S =51/2), a preferred orientation in an applied magnetic field, and slow magnetization relaxation dynamics. Strong competing magnetic exchange coupling between paramagnetic copper and manganese ions, in conjunction with high symmetry, gives rise to appreciable spin-frustration and geometric-frustration. These correlated effects lead to slow magnetization relaxation behavior. Detailed magnetization and thermodynamic studies were performed on a series of tetranuclear nickel complexes that exhibit fast magnetization tunneling and magnetic ordering. Magnetic ordering is a collective process that should drastically suppress or terminate quantum tunneling processes. It is revealed that even in an ordered state, the molecules within the crystal lattice act as single domains, thus, molecules quickly switch between magnetic ordering and single-domain quantum tunneling. A series/family of multifunctional tetranuclear manganese SMMs (magnetic and photoluminescent) were synthesized that systematically differ in co-crystallized solvate molecules and peripheral organic ligands to study magneto-structural correlation effects and quantum tunneling of magnetization. The goal is to couple emissive excited states to the magnetic moment of the SMM, which may allow, for the first time, detailed study of quantum dynamics on a 10−9-10−12s time scale.

This book was released on 2011-03-02 with total page 828 pages. Available in PDF, EPUB and Kindle. Book excerpt: At present, the marketplace for professionals, researchers, and graduate students in solid-state physics and materials science lacks a book that presents a comprehensive discussion of ferroelectrics and related materials in a form that is suitable for experimentalists and engineers. This book proposes to present a wide coverage of domain-related issues concerning these materials. This coverage includes selected theoretical topics (which are covered in the existing literature) in addition to a plethora of experimental data which occupies over half of the book. The book presents experimental findings and theoretical understanding of ferroic (non-magnetic) domains developed during the past 60 years. It addresses the situation by looking specifically at bulk crystals and thin films, with a particular focus on recently-developed microelectronic applications and methods for observations of domains with techniques such as scanning force microscopy, polarized light microscopy, scanning optical microscopy, electron microscopy, and surface decorating techniques. "Domains in Ferroic Crystals and Thin Films" covers a large area of material properties and effects connected with static and dynamic properties of domains, which are extremely relevant to materials referred to as ferroics. In other textbooks on solid state physics, one large group of ferroics is customarily covered: those in which magnetic properties play a dominant role. Numerous books are specifically devoted to magnetic ferroics and cover a wide spectrum of magnetic domain phenomena. In contrast, "Domains in Ferroic Crystals and Thin Films" concentrates on domain-related phenomena in nonmagnetic ferroics. These materials are still inadequately represented in solid state physics textbooks and monographs.

Available in PDF, EPUB and Kindle. Book excerpt: Magnetism is one of the oldest and most fundamental problems of Solid State Physics although not being fully understood up to now. On the other hand it is one of the hottest topics of current research. Practically all branches of modern technological developments are based on ferromagnetism, especially what concerns information technology. The book, written in a tutorial style, starts from the fundamental features of atomic magnetism, discusses the essentially single-particle problems of dia- and paramagnetism, in order to provide the basis for the exclusively interesting collective magnetism (ferro, ferri, antiferro). Several types of exchange interactions, which take care under certain preconditions for a collective ordering of localized or itinerant permanent magnetic moments, are worked out. Under which conditions these exchange interactions are able to provoke a collective moment ordering for finite temperatures is investigated within a series of theoretical models, each of them considered for a very special class of magnetic materials. The book is written in a tutorial style appropriate for those who want to learn magnetism and eventually to do research work in this field. Numerous exercises with full solutions for testing own attempts will help to a deep understanding of the main aspects of collective ferromagnetism.

Available in PDF, EPUB and Kindle. Book excerpt: Calculated Electronic Properties of Metals covers the significant advances in understanding of condensed systems containing many atoms. This book is divided into five chapters that specifically present electronic property calculations based on three fundamental approximations, namely, the local density treatment of electronic exchange and correlation, the "muffin-tin" approximation, and the neglect of relativistic effects. These approximations limit the range of systems for which these calculations can be expected to be accurate to metals comprised of atoms possessing fewer that approximately 50 protons. A chapter focuses on the calculation of electron and state densities of numerous metals. The concluding chapter describes the results of spin-polarized energy-band calculations for iron, cobalt, and nickel. This book will prove useful to chemists, researchers, and students.

Book excerpt: For emerging energy saving technologies superconducting materials with superior performance are needed. Such materials can be developed by manipulating the "elementary building blocks" through nanostructuring. For superconductivity the "elementary blocks" are Cooper pair and fluxon (vortex). This book presents new ways how to modify superconductivity and vortex matter through nanostructuring and the use of nanoscale magnetic templates. The basic nano-effects, vortex and vortex-antivortex patterns, vortex dynamics, Josephson phenomena, critical currents, and interplay between superconductivity and ferromagnetism at the nanoscale are discussed. Potential applications of nanostructured superconductors are also presented in the book.

Available in PDF, EPUB and Kindle. Book excerpt: The Novel Mechanisms of Superconductivity Conference was initially conceived in the early part of 1986 as a small, 2-1/2 day workshop of 40-70 scientists, both theorists and experimentalists interested in exploring the possible evidence for exotic, non phononic superconductivity. Of course, the historic discoveries of high temperature oxide superconductors by Bednorz and Mftller and the subsequent enhancements by the Houston/Alabama groups made such a small conference impractical. The conference necessarily had to expand, 2-1/2 days became 4-1/2 days and superconductivity in the high Tc oxides became the largest single topic in the workshop. In fact, this conference became the first major conference on this topic and thus, these proceedings are also the first maj or publication. However, heavy fermion, organic and low carrier concentration superconductors remained a very important part of this workshop and articles by the leaders in these fields are included in these proceedings. Ultimately the workshop hosted rearly 400 scientists, students and media including representatives from the maj or research groups in the U.S., Europe, Japan and the Soviet Union.
