摘要：

The Mn-substituted M-type Ba-ferrite (BaFe(12-x)Mn(x)O(19); x = 0, 2, 4, 6) powders were prepared by the HTTD (High Temperature Thermal Decomposition) method. The effect of Mn(3+) Jahn-Teller ions on the magnetic properties has been studied by x-ray diffraction, vibrating sample magnetometry, and Mossbauer spectroscopy. With increasing Mn substitution, the lattice parameter a(0) increases while c(0) decreases. The magnetocrystalline anisotropy constants (K(1)) were determined as 2.9, 2.2, 1.8, and, 1.3 x 10(6) erg/cm(3) for x = 0, 2, 4, and 6, respectively, by the LAS method. We have studied the change of cation distribution by Mossbauer spectroscopy which is closely related to K(1).
