The control of magnetization reversal by tuning the interlayer exchange interaction in magnetic multilayers

Abstract

The interest of noncollinear spin structures in magnetic multilayers has recently gained a lot of interest in spintronics due to the observation of unique phenomena in these systems. In magnetic multilayers coupled by the Ruderman-Kittel-Kasuya-Yosida (RKKY) interaction the study of noncollinear interactions has gained interest. In this paper, we study the magnetization reversal of two magnetic layers with different magnetic anisotropy directions coupled by the RKKY interaction. We have chosen Pt/Co/Ru/Co40Fe40B20 structures where the Pt/Co show perpendicular-magnetic anisotropy and CoFeB show an in-plane magnetic anisotropy.
