Book excerpt: Le magnétisme est l'un des plus anciens phénomènes rapportés de l'histoire des sciences naturelles et probablement l'un des plus fascinants. Véritable manifestation macroscopique de la physique quantique, il subit en s'y couplant, l'influence de nombreux réservoirs énergétiques et statistiques, dont ceux de la thermique et de la mécanique.En remarquant qu'un moment magnétique élémentaire est un objet composite formé grâce à des variables anticommutantes inobservables, on peut engendrer une dynamique Hamiltonienne couplant ce degré de liberté à ceux provenant des autres réservoirs, eux-mêmes décrits par la dynamique de variables aléatoires.La première étape est d'étudier la dynamique d'un moment magnétique, vu comme un spin classique dans de tels bains. A cette fin on considère un bain magnétique afin d'évaluer la possibilité de mimer les effets de couplage entre moments magnétique ainsi que le couplage magnétoélastique par un tel modèle effectif.Par la suite, nous montrons que la précession d'un spin classique peut être modélisée par une dynamique de Nambu qui facilite la description de la nature, additive ou multiplicative, des couplages stochastiques. La dynamique ainsi produite est d'abord étudiée numériquement de façon stochastique en moyennant les différentes réalisations obtenues; ensuite un modèle déterministe sur la hiérarchie des moments statistiques est établi puis fermé afin de développer une méthode à la fois plus rapide mais également déterministe de déduction des propriétés magnétiques.Finalement, pour illustrer la pertinence tangible de toutes ces notions, nous construisons une dynamique étendue de particules ``fictives'' portant à la fois un moment magnétique et une déformation mécanique locaux exprimant la magnétoélasticité, d'une part dans une approche Lagrangienne puis Hamiltonienne. Pour chacune des deux approches nous étudierons la dynamique du retournement ultra-rapide d'aimantation pour NiO, oxyde antiferromagnétique prototype, sous sollicitations mécanique et électrique.Le formalisme, exposé ici, aussi bien conceptuel qu'informatique, ne sert pas, seulement, comme un exemple de l'état de l'art, mais permet une description des propriétés des milieux magnétiques, qui est fondamentale aussi bien pour la conception de nouveaux matériaux, que comme modèle pour aborder d'autres questions portant sur l'interaction entre bruit et variables dynamiques, plus généralement.

Available in PDF, EPUB and Kindle. Book excerpt: This unique and comprehensive introduction offers an unrivalled and in-depth understanding of the computational-based thermodynamic approach and how it can be used to guide the design of materials for robust performances, integrating basic fundamental concepts with experimental techniques and practical industrial applications, to provide readers with a thorough grounding in the subject. Topics covered range from the underlying thermodynamic principles, to the theory and methodology of thermodynamic data collecting, analysis, modeling, and verification, with details on free energy, phase equilibrium, phase diagrams, chemical reactions, and electrochemistry. In thermodynamic modelling, the authors focus on the CALPHAD method and first-principles calculations. They also provide guidance for use of YPHON, a mixed-space phonon code developed by the authors for polar materials based on the supercell approach. Including worked examples, case studies, and end-of-chapter problems, this is an essential resource for students, researchers, and practitioners in materials science.

This book was released on 2007 with total page 738 pages. Available in PDF, EPUB and Kindle. Book excerpt: From the first application of the oxide magnetite as a compass in China in ancient times, and from the early middle ages in Europe, magnetic materials have become an indispensable part of our daily life. Magnetic materials are used ubiquitously in the modern world, in fields as diverse as, for example, electrical energy transport, high-power electro-motors and generators, telecommunication systems, navigation equipment, aviation and space operations, micromechanical automation, medicine, magnetocaloric refrigeration, computer science, high density recording, non-destructive testing of materials, and in many household applications. Research in many of these areas continues apace. The progress made in recent years in computational sciences and advanced material preparation techniques has dramatically improved our knowledge of fundamental properties and increased our ability to produce materials with highly-tailored magnetic properties, even down to the nanoscale dimension. Containing approximately 120 chapters written and edited by acknowledged world leaders in the field, The Handbook of Magnetism and Advanced Magnetic Materials provides a state-of-the-art, comprehensive overview of our current understanding of the fundamental properties of magnetically ordered materials, and their use in a wide range of sophisticated applications. The Handbook is published in five themed volumes, as follows: Volume 1- Fundamentals and Theory Volume 2- Micromagnetism Volume 3- Novel Techniques for Characterizing and Preparing Samples Volume 4- Novel Materials Volume 5- Spintronics and Magnetoelectronics

Available in PDF, EPUB and Kindle. Book excerpt: The ability to control the state of magnetic systems through electronic means is a promising challenge to those in the field of electronics and nanotechnology. The magnetoelectric effect, first predicted in 1894, is a coupling between the magnetization of a material and an electric field or the polarization of a material and a magnetic field. A lot of progress has been made since its discovery but a limited microscopic understanding of the underlying mechanisms involved, and a general weakness of the effect, makes the search for and study of these systems difficult. Recent studies have focused on considering such behaviour in low-dimensional materials or molecules. The small size and tunability of these systems makes them a worthwhile testing ground to push the limits of scale and functionality for technical applications. First-principle calculations using density functional theory (DFT) provides a computationally efficient method to characterize the ground state properties of potential magnetoelectric materials and allows the building of models that could potentially anticipate the presence and strength of the effect. In this work, we use these methods to study low-dimensional magnetic systems, one a quasi-1D molecular crystal and later, a set of single-molecule magnets.

Available in PDF, EPUB and Kindle. Book excerpt: Combining previously unconnected computational methods, this monograph discusses the latest basic schemes and algorithms for the solution of fluid, heat and mass transfer problems coupled with electrodynamics. It presents the necessary mathematical background of computational thermo-fluid dynamics, the numerical implementation and the application to real-world problems. Particular emphasis is placed throughout on the use of electromagnetic fields to control the heat, mass and fluid flows in melts and on phase change phenomena during the solidification of pure materials and binary alloys. However, the book provides much more than formalisms and algorithms; it also stresses the importance of good, feasible and workable models to understand complex systems, and develops these in detail. Bringing computational fluid dynamics, thermodynamics and electrodynamics together, this is a useful source for materials scientists, PhD students, solid state physicists, process engineers and mechanical engineers, as well as lecturers in mechanical engineering.

Book excerpt: Molecular magnets show many properties not met in conventional metallic magnetic materials, i.e. low density, transparency to electromagnetic radiation, sensitivity to external stimuli such as light, pressure, temperature, chemical modification or magnetic/electric fields, and others. They can serve as “functional” materials in sensors of different types or be applied in high-density magnetic storage or nanoscale devices. Research into molecule-based materials became more intense at the end of the 20th century and is now an important branch of modern science. The articles in this Special Issue, written by physicists and chemists, reflect the current work on molecular magnets being carried out in several research centers. Theoretical papers in the issue concern the influence of spin anisotropy in the low dimensional lattice of the resulting type of magnet, as well as thermodynamics and magnetic excitations in spin trimers. The impact of external pressure on structural and magnetic properties and its underlying mechanisms is described using the example of Prussian blue analogue data. The other functionality discussed is the magnetocaloric effect, investigated in coordination polymers and high spin clusters. In this issue, new molecular magnets are presented: (i) ferromagnetic high-spin [Mn6] single-molecule magnets, (ii) solvatomagnetic compounds changing their structure and magnetism dependent on water content, and (iii) a family of purely organic magnetic materials. Finally, an advanced calorimetric study of anisotropy in magnetic molecular superconductors is reviewed.
