研究了原位磁场退火对化学溶液沉积法制备的c轴择优取向BiFeO 3/CoFe 2 O 4多层膜的影响。结果表明，磁退火可以提高结晶质量，织构和致密化以及介电性能。此外，磁损耗随磁场的增加而减小。此外，磁退火可以提高BiFeO 3薄膜的极化强度，降低其漏电流，有利于BiFeO 3薄膜的应用。
In situ magnetic annealing effects on c-axis-preferred multiferroic BiFeO3/CoFe2O4bilayered 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 BiFeO3films.
