Mössbauer spectroscopic examination of a single crystal of

Abstract

Mössbauer spectra have been recorded in fields of up to 13 T from a single crystal of cut perpendicular to the [111] axis. The spectra were best fitted with five magnetic components complementing studies on a crystal cut normal to a [100] axis. One component corresponds to situated on the tetrahedral A sites of the inverse spinel-related structure whilst the other four correspond to and on two non-equivalent octahedral sites.
