Description

The magnetic properties of (CoxFe1−x)A(Zn1−xFe1+x)BO4 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 Padé approximant are used to calculate the critical temperature of (CoxFe1−x)A(Zn1−xFe1+x)BO4, and the critical exponent associated with magnetic susceptibility is obtained.
