dc.description.abstractNickel–zinc ferrites of different compositions, Ni 1~xZnxFe 2 O 4 with x"0.2, 0.35, 0.5 and 0.6, have been prepared by a precursor method involving citrate precursors of the concerned metals and mixing them in solution state. Resistivity has been studied as a function of composition and sintering temperature. It is observed that NiZn ferrites prepared by this method have resistivity ≤108 cm which is higher by atleast two orders of magnitude than that reported (≤106 cm) for ferrites prepared by the conventional ceramic method. This is attributed to better purity as well as better compositional and microstructural control achievable by the citrate method. High resistivity makes these ferrites suitable particularly for high-frequency losses are required to be low.en
