Nanoscale magnetic skyrmions are good candidates for data manipulation and storage in spintronic applications (logic and/or memory). A team from INAC/SPINTEC has recently shown that a gate voltage can nucleate or annihilate skyrmions. This proof of concept of a skyrmion switch paves the way towards ... More »
