Abstract
Solid solutions of La and Ba modified (1-x)BiFeO3-xPbTiO3 were prepared by the mixed oxides method. The 10 at% of La3+ and Ba2+ substituents were utilized to substitute Bi3+ and Pb2+ ions respectively. These cations enter into the crystalline lattice to modify the structure and properties of BiFeO3-PbTiO3. The morphotropic phase boundary of (1-x)(Bi,La)FeO3-x(Pb,Ba)TiO3 (BLF-PBT) appears at x=0.4 accompanying by the rhombohedral-tetragonal phase transition. It is found that (1-x)BLF-xPBT reveals enhanced ferroelectric and magnetic properties in the vicinity of the MPB. The remnant polarization and magnetization achieve of 26 muC/cm and 0.06 emu/g, respectively. Our results indicated that (1-x)Bi(Fe,Ga)O3-xPbTiO3 is of the insulating and switchable multiferroics.
