在本研究中,我们尝试通过磁光效应(MOKE)检测电流作用下铂光栅边缘的自旋积累信号。建立了一种基于偏振调制技术的MOKE探测器光学衍射仪。选用蓝色激光二极管作为光源,根据波长设计光栅。采用了交流电流和极化调制的双调制技术。目前还没有观察到自旋积累信号的显著性,表明还需要其他改进来降低背景噪声,增强自旋积累信号。
英文摘要
In this study, we attempted to detect spin accumulation signal at the edges of platinum gratings with electric current through magneto-optical effect(MOKE) .An optical diffractometer equipped with a MOKE detector based upon a polarization modulation technique was built. A blue laser diode is chosen as a light source and the gratings were designed by taking account of the wavelength.A double modulation technique of the ac current and polarization modulation was adopted. The distinct of spin accumulation signal has not been observed yet, suggesting that other improvements are needed to reduce the background noise and to enhance the spin accumulation signal.
