摘要
In situ magnetic annealing effects on c-axis-preferred multiferroic BiFeO3/CoFe2O4 bilayered by chemical solution deposition route are investigated. It is observed that magnetic annealing can enhance the crystallization quality, texture and densification as well as dielectric properties. In addition, the magnetolosses decrease with increasing the magnetic fields. Moreover, both increase of the polarization and decrease of the leakage current due to magnetic annealing are beneficial for potential applications of BiFeO3 films. (C) 2011 Elsevier B.V.
