Abstract:

Static magnetization measurements have been made on a number of compounds in the family Cd1-x-FexCr2S4 for 0orxor1. The magnetic moments at 0K fall with increasing iron content. The ordering temperatures rise and the Curie-Weiss parameters fall with increasing iron content. There is a steady decrease in lattice parameter with increasing x. A simple model is proposed in which the extra antiparallel electron on the Fe2 ion is delocalized. The band in which the electrons move is assumed to have a trap for electrons in the vicinity of the A sites. The trap allows ionic behavior at low temperatures while at higher temperatures the electrons are itinerant. The model allows a consistent understanding of the magnetic properties. Author
