摘要：

This study reports the effect of La doping on structural, morphological and magnetic characteristics of BiFeO3 synthesized under mild hydrothermal conditions at 200 degrees C for 16 h using the KOH concentration of 4 M. The as-synthesized powders of Bi1-xLaxFeO3 for x = 0.05, 0.10, and 0.15 were characterized by X-ray powder diffraction scanning electron microscope and the vibrating sample magnetometer. The formation mechanism of Bi1-xLaxFeO3 powders can be expressed by "dissolution-nucleation-crystallization" process. The magnetism of Bi1-xLaxFeO3 increased with increase of La content due mainly to increscent suppressing spiral magnetic structure and magnetic contribution of La.
