摘　　要：本文在单层CoFeB(36 nm)薄膜上构建了氧化铟锡(ITO)(10 nm)/CoFeB(36 nm)/ITO(x)/Ag(56 nm)多层异质磁纳米结构。研究发现,通过优化中间层ITO厚度(15 nm)多层异质磁纳米结构在波长为660 nm的线偏振光中的纵向克尔偏转角是单层CoFeB(36nm)薄膜磁光克尔角的2.34倍。该结构提供了一种简单实用的利用多个光学腔体调控磁性薄膜磁光克尔信号的方法,该方法将会使磁光纳米结构薄膜在生物技术、光电器件以及磁光器件等领域得到广泛应用。In this work,ITO(10 nm)/CoFeB(36 nm)/ITO(x)/Ag(56 nm)hybrid multi-layered magnetic system has been fabricated by magnetron sputtering method.In contrast to the pure CoFeB film,when the thickness of the inserted layer ITO chosen to be 15 nm,the longitudinal magneto-optical kerr rotation can be obviously enhanced 2.34 times in the wavelength of 660 nm at room temperature.This will allow us to envision such rule being employed for more ware schemes of magneto-optical nanostructures for the applications in biotechnological and optoelectronic devices.
