Abstract

Tin-doped iron chromium oxides of composition Cr2-xFexO3 prepared by the calcination of precipitates adopt the corundum-related structure.57Fe Mossbauer spectroscopy shows the materials to be composed of small superparamagnetic particles and no evidence of a Morin transition was observed above 80K.The supertransferred hyperfine magnetic field at the tin site is shown by 119Sn Mossbauer spectroscopy to be less than that experienced in tin-doped Fe2O3
