摘要: Crystalline solutions of 0.57(Bi1−xLax)FeO3−0.43PbTiO3 (BLF-PT) for x=0, 0.1, 0.2, and 0.3 have been fabricated by the solid state reaction method. The dielectric constant BLF-PT was significantly enhanced using La substitutions, reaching about 1850 x=0.3. ferroelectric-paraelectric phase transition becomes more diffused with a decreased temperature higher concentration. x=0.2 exhibits multiferroic characteristics simultaneously remnant magnetization polarization 0.119 emu/g 33.5 μC/cm2, respectively.
