Abstract

We report the synthesis of Bi _0.9 La _0.1 Fe _0.95 Mn _0.05 O ₃ (BLFMO) films with enhanced multiferroic properties and without second phase using Ba _0.7 Sr _0.3 Ti _0.95 Co _0.05 O ₃ (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. © 2017 Elsevier B.V.
