Abstract

The magnetic properties of CoFe_2-2xCr_2xO₄ 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 CoFe_2-2xCr_2xO₄ is deduced. The saturation magnetization, the coercivity field and magnetic energy are obtained.

<EA>The magnetic properties of CoFe<sub>2-2x</sub>
Cr<sub>2x</sub>

 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<sub>c</sub>
. (K) are given for the nano-spinel ferrites. The magnetic phase diagram of CoFe<sub>2-2x</sub>
Cr<sub>2x</sub>
O<sub>4</sub>
 is deduced. The saturation magnetization, the coercivity field and magnetic energy are obtained.</EA>
