Abstract
NdFe1−xNixO3 (NFNO) (x=0.0 and 0.3) perovskite structures were synthesized by ceramic method. The variation of dielectric behavior with frequency at room temperature reveals an order of enhancement in both dielectric constant and dielectric loss with 30 percent Ni substitution. UV-Visible spectroscopy data exhibit that optical energy band gap decreases with Ni substitution from 4.3eV to 4.0eV for the sample with 30% Ni doping. Magnetic disorder over some range between 1.5K and 100K is observed in SFNO samples and is explained in milieu of interaction among Nd and Fe/Ni sub-lattice moments.
