报告摘要

Spintronic devices that rely on the electron spins are promising for the application in information storage and processing. To enable high-performance spintronic devices, people are motivated to look for energy-efficient magnetization switching means and ultra-small magnetic information carrier. The spin-orbit torques (SOTs) and magnetic skyrmions, which together exhibit the above-mentioned properties, once observed have attracted tremendous attentions. This talk will introduce our recent progress on the studies of SOTs and room-temperature skyrmions in magnetic thin films, including following parts: (1) current-induced SOTs in various bilayers, such as heavy metal/ ferromagnetic metal, 2D material/ ferromagnetic metal, and heavy metal/ magnetic insulators; (2) creation and manipulation of room-temperature skyrmions for device applications.
