Abstract
A detailed study of the BiFeO3 (BFO)-based bilayer films with improved multiferroic properties is reported. The BFO film without any impurity phase was obtained using Ba0.7Sr0.3TiO3 (BSTO) as a buffer layer. And the leakage currents of the bilayer film were found to reduce effectively through La and Mn co-doping of the BFO Layer. Moreover, magnetodielectric response and ferroelectric domains were observed in the Bi0.9La0.1Fe0.95Mn0.05O3 (BLFMO)/BSTO film. We additionally investigated the effects of the BSTO-Ni0.8Zn0.2Fe2O4 (NZFO) buffer layer on the multiferroic performances and surface morphology of the BLFMO film. It was found that the BSTO-NZFO composite film could significantly enhance the magnetic and magnetodielectric properties of the BLFMO film. In particular, the BLFMO/BSTO-NZFO film possessed a higher coercivity value as compared to the BLFMO/BSTO film. © The Royal Society of Chemistry 2014.
