Abstract

Structural, electrical and magnetic properties of Bi0.9-xLa0.1ErxFeO3 (BLEFOx) (x = 0.05, 0.07, 0.1) polycrystalline ceramics prepared by solid solution route were studied. A phase transition from rhombohedral phase to monoclinic phase was observed for x=0.05-0.1 in (BLEFOx). We have measured phase transition temperatures both alpha-beta transition and low-Temperature (low-T) transitions in doped BiFeO3. The transition peak near to 835C corresponds to alpha to beta-phase transition of BiFeO3 were measured using diffential thermal analysis (DTA). Dielectric measurements shows the low-T transitions in BLEFOx (x = 0.05-0.1). Relatively high remanent magnetization of 0.1178emu/gm at 8T was observed in BLEFOx (x = 0.1).
