Zusammenfassung

Orthoferrite sind transparente Magnetwerkstoffe, die durch eine Vielzahl einzigartiger Eigenschaften (sehr hohe magnetooptische Gütezahl und Qualitätsfaktor, extrem hohe Domänenwandgeschwindigkeit) charakterisiert sind. Ihre Einsatzmöglichkeiten in innovativen mikrotechnologischen Vorrichtungen mit verbesserten Eigenschaften sind sehr vielversprechend. In dieser Arbeit werden Anwendungen von Orthoferriten zur Messung von elektrischen Strömen (Magnetfeldern) und Winkelmessungen sowie Anwendungen für die Entwicklung neuer Typen optischer Elemente, wie Trenner, Schalter und Schließer, präsentiert.

Abstract

Orthoferrites are transparent magnetic materials characterized by a number of unique features (very high values of magneto-optical figure of merit and quality factor, extremely high domain wall velocities) promising their use for the developement of various innovative micotechnological devices with improved characteristics. A review of applications in electric current (magnetic field) meters, angle measuring devices, optical modulators, switches, shutters, and isolators will be presented.
