Discrimination of skyrmion chirality via spin–orbit and –transfer torques for logic operation

Autor: Yoshinobu Nakatani, Keisuke Yamada, Atsufumi Hirohata

Publikováno v: Scientific Reports, Vol 11, Iss 1, Pp 1-6 (2021)

Abstract Recently many works on magnetic memories and logic circuits, which use a magnetic skyrmion have been reported. Previously we micromagnetically simulated a method to switch a chirality of a magnetic skyrmion formed in a magnetic thin film by
