Extended Data Fig. 8: Asymmetric imaginary impedance in the field sweep in comparison with MFM images.
From: Emergent electric field induced by dissipative sliding dynamics of domain walls in a Weyl magnet

a, Field dependence of the imaginary impedance measured when the magnetic field is decreasing, starting from high field (‘field down’ sweep). The three black dots correspond to the magnetic field values of three MFM images shown in panels b-d. b-d, MFM images taken at − 0.04 T, 0.0 T, and + 0.04 T with the field down condition. The asymmetric profile in the imaginary impedance is related to different domain configurations observed in the MFM images at + 0.04 T and − 0.04 T.
