摘要：

The effect of Zn doping on magnetic properties of Fe3O4 and CuFe2O4 ferrite spinels has been studied. The general expression of saturation magnetization, the critical temperature and Curie constant (C) are obtained by the mean field theory (MFT). By considering the high-temperature series expansions (HTSE) theory and the mean field approximation for the N,el's two-sublattice noncollinear model, we obtained the magnetic phase diagrams of Zn (x) Fe1-x Fe2O4, and Zn (x) Cu1-x Fe2O4. The Bohr magnetron is obtained for two systems. The central critical exponent gamma associated with magnetic susceptibility for two systems is obtained.
