摘要：
The properties of α-Fe2O3 fine particles with and without adsorbed pyridine were studied by Mossbauer spectra. The effective anisotropy constant K were calculated. The K of pyridine- adsorbed a -Fe2O3 particles is smaller than that of pure α-Fe2O3 particles. A probable mechanism of the decreasing effective anisotropy constant K is discussed.
