BiFeO3薄膜研究进展

BiFeO3是少数的在室温下同时具有铁磁性和铁电性的铁磁电材料之一,在信息存储、传感器和自旋电子器件等方面都有潜在的应用前景.本文通过对BiFeO3薄膜的结构、磁性起源、制备工艺和应用领域等方面的综述,提出并设计了水热法和仿生法这两种新的制备BiFeO3薄膜的湿化学方法,并展望了BiFeO3薄膜今后的研究和发展趋势.

Research Progress on BiFeO3 Thin Films

BiFeO3, one of very few multiferroics with a simultaneous coexistence of ferro electric and antiferromagnetic at room temperature, has potential applications i n memory devices, sensors and spintronics devices et al. Through the summarizati on of BiFeO3 thin films in its crystal structure, origin of magnetic, preparin g technologies and applying fields, two novel wet chemical processes including h ydrothermal method and bimimetic technique for depositing BiFeO3 thin films we re designed and suggested. The development of BiFeO3 thin films was also prosp ected.
