Abstract
The effect of Ce4+ substitution in NiFe2O4, with the chemical formula Ni1−2xCexFe2O4 (0 ⩽ x ⩽ 0.25), is presented in this paper. The Ce4+ ion increases the DC resistivity of the NiFe2O4. The dielectric constant (ε′) decreases with frequency as well as with composition. Infrared spectroscopy is employed to determine the local symmetry in crystalline solids and to shed light on the ordering phenomenon. The band frequency ν1 decreases slightly with increasing Ce4+ concentration, whereas ν2 remains almost constant.
