摘要：
The crystal structure, microstructure, and magnetic properties of Bi0.84La0.16Fe1-xTixO3 (x = 0.1, 0.14, 0.16, 0.2) ceramic samples prepared by solid-state reaction are investigated by combining X-ray diffraction, Raman scattering, scanning electron microscope, and magnetic measurements. The analysis of crystal structure reveals the presence of multiphase structures and the gradual formation of Aurivillus Bi5FeTi3O15 phase when increasing Ti concentration. The microstructure study shows several grain shapes, corresponding to the different crystal structures and phases present in the sample. The competition in lattice strain of the coexisting phases leads to the isothermal structural transition and the self-change in magnetization. A drastic decrease in coercivity and an increase in magnetization are observed with increasing ferromagnetic-like hysteresis loops. The change in magnetic properties of the samples is strongly dependent on the coexisting phases in the samples.
