Masrour, M. Hamedoun, A. Benyoussef] The magnetic properties of CoFe2−2x Cr2x O4 spinels are studied by different theoretical methods: the mean field theory, the high-temperature series expansions (MFT, HTSE) and the probability distribution law with the different size L (nm). The exchange interactions and the critical temperature T c (K) are given for the nano-spinel ferrites. The magnetic phase diagram of CoFe2−2x Cr2x O4 is deduced. The saturation magnetization, the coercivity field and magnetic energy are obtained.
