Abstract

In the present work we are reporting the dielectric properties of the samples having chemical composition Bi1-xNdxFeO3 (x = 0, 0.05, 0.10, 0.15), prepared by the solution combustion technique. The SEM investigation has suggested that the Nd substitution hinders the grain growth. In dielectric measurements it has been found that Nd substitution significantly improved the dielectric behaviour of the compound. Temperature dependence of dielectric constant showed the signs of magneto-electric coupling in the samples. The anti-ferromagnetic to paramagnetic transition temperature (T-N) obtained by M-T and DSC measurements was found to be in good agreement with the temperature response of dielectric constant. The ac conductivity of the samples has been found to decrease with increasing Nd content, which is desirable from the technological point of view.
