Assessment of the critical behavior near the FM to PM phase transition in cubic Ni0.3−xCuxZn0.7Fe2O4 spinel ferrite

•Results show that the ferromagnetic–paramagnetic transition is of second order.•The critical exponents (β, γ and δ) values for Zn0.7Ni0.3−xCuxFe2O4 are close the 3D-Heisenberg model.•The obtained values of critical exponents satisfying the scaling theory. In this study, we report a thorough examina...
