Enhanced electric and magnetic properties of (BiLi)1/2(Fe2/3W1/3)O3 multiferroic as compared to BiFeO3

Very low electric and magnetic moments are the two major disadvantages which restrict the practical applications of BiFeO3. We have doped Li+ and W6+ in Bi3+ and Fe3+ site respectively to overcome the limitations of BiFeO3. Pure BiFeO3 and (BiLi)1/2(Fe2/3W1/3)O3 (BLFWO) are synthesized by a solid-state reaction technique. The samples are characterized by X-ray diffractometer, LCR meter, P-E loop tracer, vibrating sample magnetometer and dc resistivity setup to understand their different properties. Dielectric and impedance studies of the samples are measured at different frequency (102-106 Hz) in a wide temperature range (30-375 °C). Due to co-doping in pure BFO the remnant polarization and remnant magnetization are enhanced and thus BLFWO may show large industrial utility.
