ABSTRACT: Ni0.5Cu0.25Zn0.25GdxFe2-xO4 (x = 0.0, 0.025, 0.05, 0.075, 0.1) ferrites were synthesized using an
oxalic-based precursor method. The TC for all the Ni0.5Cu0.25Zn0.25GdxFe2-xO4 (x = 0.0, 0.025, 0.05, 0.075, 0.1) samples was measured by using one of the double coil susceptibility setup. In all the samples it is observed that, at a
certain temperature, susceptibility falls to zero indicating the Curie
temperature (TC) and ferrimagnetic samples are converted into
paramagnetic sample at that temperature. The electrical properties were
investigated for these samples. Dielectric properties and ρdc properties were observed to decrease with the
increase in the frequency for all the Gd doped ferrite samples.
