摘要：

The magnetic properties of (CoxFe1-x)(A)(Zn1-xFe1+x)(B)O-4 are studied using mean-field theory and the probability distribution law to obtain the saturation magnetization, the coercive field, the critical temperature, and the exchange interactions with different values of D (nm) and x. High-temperature series expansions (HTSEs) combined with the Pade approximant are used to calculate the critical temperature of (CoxFe1-x)(A)(Zn1-xFe1+x)(B)O-4, and the critical exponent associated with magnetic susceptibility is obtained.
