Abstract

Abstract: Magnetic skyrmions are a topologically stable spin configurations that are currently extensively studied as promising information carriers in spintronic devices. When an electric current is injected, the skyrmions exhibit the skyrmion Hall effect. This skyrmion Hall effect can be described by the Thiele equation. Here, we experimentally examined the validity of the Thiele equation. For this study, a series of Pt/Co/W films with a wide range of Co layer thicknesses were examined. The results verified the Thiele equation of the skyrmion Hall angle as a function of the magnetic anisotropy and Gilbert damping constants.
