摘要

Magnetic properties and exchangecoupling interactions of diluted magnetic spinels A_(1-x)A′_xB_2X_4, where A and B are magnetic ions, namely Co_(1-x)Mg_xFe _2O_4, were investigated using the high-temperature series expansion method (HTSE) and the distribution method of magnetic cations in the range 0≤x≤1. The magnetic phase diagram and transition temperature versus dilution x were determined using the Padé approximants method along with HTSE. The critical exponent associated with the magnetic susceptibility γ was then deduced. The obtained results are in good agreement with experimental results and critical exponent values are consistent with those suggested by the universality hypothesis.
