Fig. 2: First and second harmonic voltages.
From: Observation of magnonic spin-orbit torque in epitaxial Co films
Angular dependencies of the first harmonic voltages: a longitudinal and b transverse, measured for a current amplitude of I0 = 16 mA under 59.1 mT and 670.0 mT with φEA = 45°. Angular dependencies of the second harmonic voltages measured for a current amplitude of I0 = 16 mA under different external fields with φEA = 45°: c longitudinal and d transverse. The solid curves represent fitting results of the low magnetic field model. The variation of vertical axes are determined by the scale bars in the diagrams.
