Figure 3. Characterization of the current-induced effective fields. (a)-(b) The 1st and 2nd harmonic Rxx and Rxy as a function of the azimuthal angle φ at 6 K and 4 T. (c) The symmetric and antisymmetric components of the second-harmonic Rxy. (d) The fitting curves of the symmetric second-harmonic Hall resistances. (e) - (f) The damping-like and field-like effective fields as a function of the ac current at 6 K.
