Description

The emerging interfacial Dzyaloshinskii-Moriya interaction (iDMI) can lead to fast current-driven domain wall motion and the formation of topological magnetic skyrmions, which is promising for the design of high performance spintronic devices. Here, a nanometric island of Pt/Co/AlOx (Al) was fabricated with patterned regions of varying out-of-plane and in-plane magnetic anisotropies. We observed that, due to iDMI, the magnetization orientation of adjacent out-of-plane and in-plane regions satisfy the chirality. This chiral coupling between out-of-plane and in-plane magnetization might offer a platform to design novel lateral coupled nanomagnetic system.
