Abstract

Coprecipitation of manganese and iron followed by calcination at temperatures below 500°C results in a new structural phase for the Mn-Fe-O system: a non-stoichiometric spinel with, in every three unit cells, one metal atom missing. About 57% of the iron in this spinel has the composition γMnFeO₃ which is paramagnetic at room temperature. The remaining 43% of the iron has the composition Mn_yFe_2-yO₃ with y∼0.16 which is magnetic at room temperature.
