Iron-doped BaTiO3: Influence of iron on physical properties

Abstract

Barium Titanate BaTiO3 is known for both its electric and magnetic properties. The synthesis and characterization of iron doped barium titanate; BaTi1-xFexO3 (x= 0.005, 0.01, 0.015) was investigated with a view to understand its structural, magnetic and electrical properties. A finest possible sample of Iron doped micro particles of BaTiO3 (BTO) with possible tetragonal structure via a solid-state route was prepared. Prepared samples of BaTi1-xFexO3 (Fe-BTO) were structural characterized by X-ray diffraction (XRD) then XRD data fitted by Rietveld refinement. Fourier Transform Infrared Spectroscopy were use to determine the Ti-O bond length position according to increment in Iron on Titanium site. The dielectric constant measurements of the samples were carried out at 1 MHz. Vibrating Sample Magnetometer (VSM) measurements revealed the magnetic nature of Iron doped BaTiO3. Magnetic Moment verses Temperature plot took at 1Tesla and Magnetic Moment verses Magnetic field plot took at low temperature (10K). Ferroelectric hysteresis loop traced at the electric field in-between -8 to +8 (KV/cm). Details of the preparation technique, experimental results, data analysis, and the interpretation will be presented.
