From: Chiral transport along magnetic ___domain walls in the quantum anomalous Hall effect
Experimental summary. a Hysteresis curves of the Hall (red) and longitudinal (blue) resistivities in a top-gated Hall bar of the magnetic topological insulator (Cr0.12Bi0.26Sb0.62)2Te3. b Schematic side view of a superconducting cylinder screening magnetic flux lines away from a thin MTI film (purple) on a GaAs substrate (blue). The cylinder and MTI are separated by an alumina dielectric (brown) and a top gate (gold). Dimensions are not to scale. c Schematic top view of Device A. d Schematic top view of Device B. e, f Schematics of the expected chiral electrical transport in the presence of magnetic ___domain walls (dotted lines), when M z  = −1 and \(M_{z}^{\rm {SC}} = 1\), in Devices A and B. The orange arrows indicate a single chiral mode each, and the red and blue vectors indicate the direction of magnetization.
