Title: Effects of Ni{sup 3+} substitution on structural and temperature dependent dielectrical properties of NdFeO{sub 3}

The polycrystalline samples of NdFe{sub 1−x}Ni{sub x}O{sub 3} (x=0.0, 0.2) were prepared by solid state reaction route, the single phase of powdered samples were ensured by Rietveld refinement of their X-ray diffraction (XRD) data. We have also studied the variation of dielectric constant (ε′), tangent loss (tan δ) and AC conductivity (σ{sub ac}) as a function of frequency and temperature for both the compositions. It is noticed that both the increase in temperature and Ni{sup 3+} ion substitution results in enhancement of dielectric constant, tangent loss and AC conductivity.
