Crystallized Bi0.9La0.1Fe0.95Mn0.05O3/Ba0.7Sr0.3Ti0.95Co0.05O3 bilayer thin films with enhanced multiferroic properties
We report the synthesis of Bi0.9La0.1Fe0.95Mn0.05O3 (BLFMO) films with enhanced multiferroic properties and without second phase using Ba0.7Sr0.3Ti0.95Co0.05O3 (BSTCO) film as a buffer layer. Sol-gel processes were used to prepare the crystallized BLFMO/BSTCO films, in which magnetic domains were observed and no impurity phase was detected. We found that the buffer layer could effectively enhance the saturation magnetization and retentivity values of the BLFMO films, and especially the magnetic coercive field of these bilayer films was significantly stronger than that of the BLFMO films without buffer layers.
