1 Fig. 3 Measurement of SOT efficiency (θDL,m) from ST-FMR.
Measurement of SOT efficiency (θDL,m) from ST-FMR. (A) Schematics of measurement setup. The moment m in Py follows an elliptical precession route around the direction of H. It is influenced by two orthogonal torques τFL and τDL. Top right shows the optical image of the device and electrode (dark color). (B) Voltage spectra of L10-IrMn (22)/Py (17) measured from 8 to 12 GHz with nominal input power of 18 dBm. (C) Typical fitting of Vmix at 9 GHz. Vsym and Vasym correspond to the symmetric and antisymmetric components, respectively. (D) Fitting of Kittel equation. (E) θDL,m of L10-IrMn, p-IrMn, and Pt. The error bar describes 1 SD over at least five devices. Jing Zhou et al.
