摘要

研究了单域铁氧体铋（BiFeO3）薄膜在外加电场和光照射下的磁光克尔效应（MOKE）。场扫 MOKE 测量表明，在外加电场或光照射下，BiFeO3 的克尔旋转发生了变化。压电响应力显微镜测量发现，在外加电场和紫外线照射下，BiFeO3 表面的电极化变化相似，这证实了 BiFeO3 的克尔旋转可同时受电场和光照射的控制。本文提出了一种通过测量 BiFeO3 的克尔角实现磁场与电场或光照射耦合的方法，为制造氧化物电子学中的多功能器件提供了一个概念。

Measurement of the coupling of magnetism with electricity or light irradiation in BiFeO3 using the Kerr angle

The magneto-optical Kerr effect (MOKE) in monodomain bismuth ferrite (BiFeO3) thin films was investigated under applied electric fields and light irradiation. The field-swept MOKE measurements show that the Kerr rotation of BiFeO3 changes under applied electric fields or light irradiation. The piezoresponse force microscopy measurements found that the variation in electrical polarization at the BiFeO3 surface was similar under an applied electric field and ultraviolet irradiation, confirming that the Kerr rotation of BiFeO3 can be controlled using both electric fields and light irradiation. This paper presents a method to couple a magnetic field with an electric field or light irradiation via the Kerr angle measurements of BiFeO3, providing a concept for fabricating multifunctional devices in oxide electronics.
