A temperature and magnetic field dependence M?ssbauer study of ?-Fe2O3

Abstract  ɛ-Fe2O3 was synthesized as nanoparticles by a pre-vacuum heat treatment of yttrium iron garnet (Y3Fe5O12) in a silica matrix at 300°C followed by sintering in air at 1,000°C for up to 10 h. It displays complex magnetic prop
