Abstract
The magnetic properties of Ni-Mg ferrites with compositions Ni1-xMgxFe2O4, have been studied using the mean field theory and high temperature series expansion theory (HTSE), extrapolated with the Padé approximants method. The nearest neighbour super-exchange interactions for intra-sites and inter-sites of the Ni-Mg ferrites in the range 0 ≤ x ≤ 1 have been computed using the distribution method of magnetic cations. The transition temperature TC is calculated as a function of Mg concentration. The critical exponent associated with the magnetic susceptibility 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.
