摘要：

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)O-3 (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 (10(2)-10(6) Hz) in a wide temperature range (30-375 degrees C). Due to co-doping in pure BFO the remnant polarization and remnant magnetization are enhanced and thus BLFWO may show large industrial utility. (C) 2016 Elsevier Ltd and Techna Group S.r.l.
