Abstract

Magnetic skyrmions might be used as information carriers in future advanced memories, logic gates and computing devices. However, there exists an obstacle known as the skyrmion Hall effect (SkHE). Consequently, the skyrmions in constricted geometries may be destroyed by touching the sample edges. In this proposed invited talk, Dr. Zhou will talk about his recent research results of skyrmion motion in the antiferromagnetically exchange-coupled bilayer system, where a pair of SkHE-free magnetic skyrmions can be nucleated and be driven by the current-induced torque [1-4]. This work provides a promising means to move magnetic skyrmions in a perfectly straight trajectory in ultra-dense devices with ultra-fast processing speed.
