Magnetic order in tin-doped thiospinels

The tin-doped sulphur-containing compound of composition Fe1.05Cr1.90Sn0.05S4, in which tin is located on the octahedral sites as Sn(IV) in the spinel-related structure, has been examined by 119Sn Mössbauer spectroscopy. The data complement results obtained by 57Fe Mössbauer spectroscopy and show that tin doping increases the magnetic ordering temperature of pure FeCr2S4. These results are compared with the data obtained on tin-doped CuCr2X4 compounds (X = O, S, Se).
