The M?ssbauer spectra, the magnetic properties, neutron diffraction and X-ray pho-toelectron spectra of pure and Co coated α-Fe2O3 have been measured. It is found that the Morin transition temperature of α-Fe2O3 is influenced and the eoercivity is increased obviously by Co coating. We suggest that a fine structure (single ion) anisotropy energy constant Kfs would be decreased by Co coating, this could explain the experimental results.
