Multiferroic Properties of La-Rich BiFeO₃-PbTiO₃Solid Solutions

Abstract

Abstract La rich (BF0.50–LF0.50)1-x–(PT)x (BLF-PT) (where x = 0.34, 0.40, 0.50 and 0.60) has been investigated. Solid solutions were prepared using conventional solid-state reaction route. Solid solutions x ≤ 0.50 exhibit rhombohedral structure and x = 0.60 has tetragonal structutre. It is established that the MPB of these solid solutions is shifted to 40:60 with La doping. Enhancement in dielectric, ferroelectric, magnetic properties have been observed. La doping also observed to reduce the dielectric losses and leakage current.
