Abstract We report direct magneto-optical measurements in epitaxial films of bismuth-substituted ferrite garnets that shown the magnetic domain walls can be reversibly changed under an electric field due to the magneto-electric effect. Electric field-induced bending or elongation of domain walls local areas was observed by us using the method of optical polarimetry. Upon removal of the electric field, the domain walls of the magnetic film return to their original configuration.

电场感应微磁结构元素在薄铁氧体石榴石薄膜中的运动

摘要 我们报告了铋取代铁氧体石榴石外延膜的直接磁光测量结果，表明磁畴壁由于磁电效应可以在电场下可逆地改变。我们使用光学偏振法观察了电场引起的畴壁局部区域的弯曲或伸长。去除电场后，磁膜的畴壁恢复到其原始配置。
