Mössbauer spectroscopic examination of a single crystal of

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.
