Abstract
The ferroelectric compound barium titanate (BaTiO3) has a perovskite type structure. It is an essential material for dielectric applications. From application point of view, doped BaTiO3 ceramic materials inherit great potential for electric and electronic devices. Herein, the Fe doped BaTiO3 is reported. It was synthesized by solid-state reaction route. The structural, vibrational and electric properties of BaTiO3 were studied using X-ray powder diffraction (XRD), Raman spectroscopy and Polarization (P-E loop) characterizations. The study of XRD pattern of Fe doped BaTiO3 reveals that the sample has acquired single phase tetragonal structure with space group P4mm. The Raman spectra obtained at Room temperature for Fe doped BaTiO3 display signature Raman modes witnessing tetragonal structure. The P-E hysteresis loop of Fe doped BaTiO3 displays a good behaviour with definite saturation and remnance of polarization however the cut in loop reveals the sample exhibits leakage.
