<br/><br/> Nanometric nickel copper ferrites Ni₁₋  CU  Fe₂O₄ , Ox O.45 were prepared by the citrate precursor method . XRD measurements confirm the formation of single phase cubic spinel structure . The lattice parameter increases with increasing CU²⁺ ion substitution . The decrease in the ac conductivity was ascribed to the increase in hopping length
