Multiferroic Properties of La, Ba Co-Modified BiFeO 3 -PbTiO 3 Crystalline Solutions
Solid solutions of La and Ba modified (1-x)BiFeO<sub>3</sub>-xPbTiO<sub>3</sub> were prepared by the mixed oxides method. The 10 at% of La<sup>3+</sup> and Ba<sup>2+</sup> substituents were utilized to substitute Bi<sup>3+</sup> and Pb<sup>2+</sup> ions respectively. These cations enter into the crystalline lattice to modify the structure and properties of BiFeO<sub>3</sub>-PbTiO<sub>3</sub>. The morphotropic phase boundary of (1-x)(Bi,La)FeO<sub>3</sub>-x(Pb,Ba)TiO<sub>3</sub> (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)O<sub>3</sub>-xPbTiO<sub>3</sub> is of the insulating and switchable multiferroics.
