Magnetic and dielectric behaviors of Ba0.2Sr0.8Co0.8Fe0.2O3-δ oxide Original Research Article

Ba0.2Sr0.8Co0.8Fe0.2O3-δ (BSCFO) ceramic oxide has been synthesized by combined citrate–EDTA complexing method and studied with regard to their structural, magnetic and dielectric properties. It is shown that the compound exhibits perovskite-type cubic structure. It depicts hysteresis loop in presence of magnetic field—indicating its magnetic nature. The dielectric properties of sintered oxide were investigated in temperature range (373–873 K) and frequency (100 kHz–1 MHz).The ferroelectric and ferrimagnetic transition temperatures were found to be around 700 K.
