Electron Spin Resonance in Frustrated Two- and Three-Dimensional Chromium Magnets

125 Seiten, Dissertation Universität Augsburg (2011), Softcover, B5

Zusammenfassung / Abstract

The aim of the present thesis was to give an overview on the abilities of electron spin resonance (ESR) as a microscopic probe for spin correlation phenomena in Cr3+ based two- and three-dimensional oxides and chalcogenides. The physics of these series of compounds is intimately connected with the partially filled electronic 3d shell of the Cr3+ ions. Direct information on the local susceptibility and the dominant magnetic interactions are accessible from the respective parameters: ESR intensity, g value, and linewidth.
