Abstract

Tin-doped compounds of spinel-related M3O4 (M = Fe, Mn, Co) have been studied by 119Sn and 57Fe Mssbauer spectroscopy in the temperature range of 20–600 K. The 119Sn Mssbauer spectra recorded down to 20 K from the non-iron-containing compounds of Co3O4 and Mn3O4 contained only doublets showing no transfer of magnetic properties from cobalt or manganese to the dopant tin ions. In contrast, the tin-doped-(FeCo)3O4 and (FeMn)3O4 gave 119Sn and 57Fe Mssbauer spectra, which showed magnetic hyperfine interactions. The Curie temperature has been estimated for the former sample.
