摘要：

The properties of alpha-Fe2O3 fine particles coated with cobalt and pyridine have been investigated by means of magnetic measurements and Mossbauer spectra. The Morin transition temperature T(M) for Co-coated alpha-Fe2O3 decreases and that for pyridine-coated alpha-Fe2O3 increases, comparing with the pure alpha-Fe2O3. The angles between <111> axis and the spin of iron ions for these samples have been calculated from the quadrupole splitting.
