Abstract
Nanocrystelline La1−xSrxFeO3 (0≤x≤1) was prepared by sol gel citrate method. The structural characterization of the compound was carried out by XRD and SEM. X-Ray diffraction showed that single phase LaFeO3 was formed with an orthorhombic structure. DC measurements of the prepared material were investigated from 300K-400K. It has been observed that increase in Sr content enhances the conductivity. The non-linearity in IV curves indicates that the Poole-Frenkel mode of conduction hold for such system.
