The magnetic properties of spinel ferrites [Fe1-(1-x)y3+Cu(1-x)y2+](A)[Nix2+Cu(1-x)(1-y)2+Fe1+(1-x)y3+](B)O-4 have been studied by the mean field theory(MFT) and high temperature series expansions (HTSEs) combined with the Pade approximants. The critical temperature, the saturation magnetisation(M-S) and the intra-sublattice exchanges interactions (J(AA)(x,y), J(BB)(x,y) and J(AB)(x,y)) are obtained by using a probability distribution law. The critical exponents associate with the magnetic susceptibility have been obtained. The effect of copper doping on the magnetic properties of nickel ferrites has been examined.
