| Abstract: | The magnetic properties of (Cox Fe1-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 Pad′e approximant are used to calculate the critical temperature of (Cox Fe1-x) A (Zn1-x Fe1+x) BO4 , and the critical exponent associated with magnetic susceptibility is obtained. |
