Multiferroic behaviour in ‘Bi’ doped solid solution SmFeO3-BaTiO3 perovskite system

Abstract

The solid solution of (Sm0.75Bi0.25FeO3)0.5 (BaTiO3)0.5 perovskite system is developed through conventional solid state reaction route. Prepared compound is thoroughly analyzed for its multipurpose use by studying its multiferroic character. The XRD spectra verifies the synthesized material is crystallize in tetragonal structure (space group = P4mm). The identification of the involved elements and their actual oxidation states are inspected through X-ray photoelectron spectroscopic (XPS) technique. Dielectric studies reveal the material has high dielectric constant at room temperature for possible storage devices. The relaxation process in the system is related to the short-range portability of charge transporters as studied from modulus spectra. Material can be beneficial for memory devices according to the room temperature multiferroic studies.
