抄録
内容記述 Compositional dependence of spin–orbit torque (SOT) of the bilayer comprised of Ta and ferrimagnetic GdFeCo was investigated. Critical current density of SOT switching J sw of the GdFeCo/Ta bilayers did not vary with Gd composition x, and were found to exhibit roughly J sw = 11 MA cm^−2. Two orthogonal components of SOT, damping-like torque τ DL and field-like torque τ FL were estimated by measuring harmonic Hall resistance under in-plane fields parallel and perpendicular to the AC current, respectively. The absolute values of SOT, midτ DLmid and midτ FLmid, were confirmed to be roughly constant within 22 ≤ x ≤ 28. On the other hand, the sign of τ FL changed across the compensation composition. These results suggest that the injected spin current is considered to exert a torque to the transition metal FeCo moment rather than to the rare earth Gd moment.
