This book, in the broadest sense, is an application of quantum mechanics and statistical mechanics to the field of magnetism. Under certain well described conditions, an immensely large number of electrons moving in the solid will collectively produce permanent magnetism. Permanent magnets are of fundamental interest, and magnetic materials are of great practical importance as they provide a large field of technological applications. The physical details describing the many electron problem of magnetism are presented in this book on the basis of the density functional approximation. The emphasis is on realistic magnets, for which the equations describing properties of the many electron problem can only be solved by using computers. The significant recent and continuing improvements are, to a very large extent, responsible for the progress in this field. Along with an introduction to the density functional theory, the book describes representative computational methods and detailed formulas for physical properties of magnets which include among other things the computation of magnetic ordering temperatures, the giant magneto-resistance, magneto-optical effects, weak ferromagnetism, the anomalous Hall and Nernst effects, and novel quasiparticles, such as Weyl fermions and magnetic skyrmions.

This book, in the broadest sense, is an application of quantum mechanics and statistical mechanics to the field of magnetism. Under certain well described circumstances, an immensely large number of electrons moving in the solid state of matter will collectively produce permanent magnetism. Permanent magnets are of fundamental interest, and magnetic materials are also of great practical importance as they provide a large field of technological applications. The physical details describing the many electron problem of magnetism are presented in this book on the basis of the local density functional approximation. The emphasis is on realistic magnets, for which the equations describing the many electron problem can only be solved by using computers. The great, recent and continuing improvements of computers are, to a large extent, responsible for the progress in the field. Along with a detailed introduction to the density functional theory, this book presents representative computational methods and provides the reader with a complete computer programme for the determination of the electronic structure of a magnet on a PC. A large part of the book is devoted to a detailed treatment of the connections between electronic properties and magnetism, and how they differ in the various known magnetic systems. Current trends are exposed and explained for a large class of alloys and compounds. The modern field of artificially layered systems - known as multilayers - and their industrial applications are dealt with in detail. Finally, an attempt is made to relate the rich thermodynamic properties of magnets to the ab initio results originating from the electronic structure.

Masterarbeit aus dem Jahr 2024 im Fachbereich BWL - Allgemeines, Note: 1,0, Fachhochschule des bfi Wien GmbH, Sprache: Deutsch, Abstract: Bierjurys sind derzeit mit einer Reihe von Veranderungen in ihrem Umfeld konfrontiert. Hinzu kommt die Digitalisierung, die sowohl als Herausforderung als auch als Potenzial fur Bierjurys gesehen werden kann. Ziel dieser Arbeit ist es, einen Beitrag zum Verstandnis und zur Bedeutung des Themas der digitalen Transformation fur Bierjurys zu leisten und Handlungsempfehlungen fur Veranstalter von Bierwettbewerben zu zukunftig notwendigen Anpassungen des eigenen Geschaftsmodells zu entwickeln, um den identifizierten Herausforderungen erfolgreich zu begegnen. Methodisch stutzt sich die Arbeit auf Literaturrecherche und Experteninterviews. Es werden Organisatoren von Bierwettbewerben und Verantwortliche von Brauereien (als Kunden der Bierwettbewerbe) befragt, um unterschiedliche Perspektiven auf das Geschaftsmodell von Bierwettbewerben zu gewinnen. Als Ergebnis der Recherche und der qualitativen Interviews kann festgehalten werden, dass die Digitalisierung eine Reihe von Innovationspotenzialen fur das Geschaftsmodell von Bierjurys bietet, die sich vor allem auf die Infrastruktur, die Prozesse, das Leistungsversprechen, die Kanale zur Interaktion mit den Brauereien und die Hohe der Kosten positiv auswirken. Damit konnen die Herausforderungen von Bierwettbewerben erfolgreich bewaltigt werden. Mit den Geschaftsmodellvarianten Prozessdigitalisierung , Digitale Bewertung , Digitale Forderung und Digitale Plattform wurden vier verschiedene Formen eines zukunftigen Geschaftsmodells identifiziert und entsprechend in einem Business Model Canvas skizziert. Zudem werden praktische Auspragungen der Modelle aufgezeigt.
