Nanocrystalline Mg-Zn ferrite is prepared by ball milling the stoichiometric powder mixture of MgO, ZnO and a-Fe 2 O 3 . The ternary Mg-Zn ferrite phase may not be obtained by heat treatment of the stoichiometric powder mixture of the oxides. The particle size of ferrite phase in the ball milled sam
