Structural, dielectric and magnetic behavior of BST modified rare earth ortho-ferrite LaFeO3

This communication reports the effect of rare earth ortho-ferrite LaFeO3 on the structural, micro-structural, dielectric, electrical, conduction and magnetic behaviors of BST i.e. [(LaBa0.5Sr0.5)(0.5)(FeTi)(0.5)O-3]. After successful preparation of sample in desired conditions by the conventional solid state route, its single phase formation in orthorhombic symmetry have been analyzed and confirmed by X-ray diffraction technique. The compound shows improved optical, dielectric and magnetic behavior. The dielectric and electrical characteristics of the sample has been studied in different conditions of temperature (25-500 degrees C) and frequency (11000 kHz). A thermally activated transport characteristic evidences the semiconductor nature of the sample. Room temperature magnetic hysteresis confirms the presence of sizeable ferromagnetism in the studied compound. Based on other interesting results, this material could be considered favorable candidate for electronic device applications.
