Mg-Mn-Ni ferrites of different compositions, Mg
x = 0.00
were prepared by a co-precipitation technique at 30°C to 60°C. Their structural and dielectrical properties were studied using XRD, SEM and AFM analyses, FT-IR technique and impedance analyses. From these, we observed that Mg-Mn-Ni ferrites prepared by this method have higher resistivity than that prepared by the conventional ceramic method and others. Higher resistivity ferrite materials are suitable particularly for high-frequency applications where eddy current losses are required to be low.
