摘要：

Crystalline solutions of 0.57(B1-xLax)FeO3-0.43PbTiO(3) (BLF-PT) for x=0, 0.1, 0.2, and 0.3 have been fabricated by the solid state reaction method. The dielectric constant of BLF-PT was significantly enhanced by using I-a substitutions, reaching about 1850 for x=0.3. The ferroelectric-paraelectric phase transition of BLF-PT becomes more diffused with a decreased transition temperature for higher L,a concentration. BLF-PT of x=0.2 exhibits multiferroic characteristics with the simultaneously enhanced remnant magnetization and polarization of 0.119 emu/g and 33.5 mu C/cm(2), respectively.
