The proposed multiferroic compound (BiBa0.5Sr0.5)0.5(Fe0.5Ti0.5)O3 (BFO–BST) is processed to investigate the effect of (Ba0.5Sr0.5)TiO3 on the structural and multiferroic behaviour of BFO. The sample was tailored by the conventional solid state route at a moderate temperature. SEM, XRD, RAMAN and FTIR characterization technique give the information about the single phase formation of the compound. The SEM image reveals the high density of the compound. The multiferroic behavior of the studied compound has been verified by studying its room temperature polarization as well as magnetization. The variation of dielectric constant and tangent loss with temperature and frequency gives the information about electric and dielectric behavior of the compound. Optical aspects of the ceramic are analyzed by using UV–Vis spectroscopy technique. Diffuse reflectance and absorbance data are used to measure the optical band gap of the compound and is estimated as 1.75 eV.
