Magnetism: Molecules to Materials IVJoel S. Miller, Marc Drillon Magnetische Phänomene und Materialien umgeben uns überall. Jüngste Fortschritte in der Chemie, den Materialwissenschaften und der Festkörperphysik geben uns neue, aufregende Einsichten in das magnetische Verhalten von Materie. Das Spektrum reicht von organischen, (bio-)anorganischen und Hybridverbindungen bis hin zu metallischen Materialien und ihrer Oxide, welche beispielsweise dünne Filme, Nanopartikel oder -drähte formen. Die Erforschung magnetischer Phänomene eröffnet ganz neue Perspektiven für viele kommerzielle Anwendungen der Zukunft - die Durchführung von chemischen Reaktionen in magnetischen Feldern ist nur eine davon. Diese offene Buchreihe bietet eine umfassende Übersicht über die aktuelle Forschung und Entwicklung auf diesem interdisziplinären Gebiet. Alle Beiträge stammen von ausgewiesenen Experten, welche die neuesten Forschungsentwicklungen, den Zusammenhang zwischen elektronischer Struktur und magnetischen Eigenschaften in anschaulicher Weise beschreiben. Aufgrund seiner ausgewogenen Verbindung von Theorie und Praxis hilft das Buch nicht nur bei der richtigen Beurteilung von experimentellen Beobachtungen, sondern dient darüber hinaus als Basis für das Design neuer magnetischer Materialien. - Ein unverzichtbares Referenzwerk für alle Diplomanden, Doktoranden und Forscher, die im Bereich Chemie, Materialwissenschaften oder Physik an magnetischen Materialien arbeiten! |
