Effect of Mg substitution on the magnetic properties of Ni–Zn ferrites
Nickel–zinc ferrites with the general chemical formula, Ni 0.3 Zn 0.7 - x Mg x Fe 2 O 4 with x varying from 0.00 to 0.25 in steps of 0.05, have been prepared by conventional solid-state method. Final sintering of the samples was carried out at 1200 ∘ C for 6 h in air to investigate their structural...
