Figure S1. (a) Plot of logρ_yz^A against logρ_zz for HoMn6Sn6. (b) Full logarithmic plot of σ_xy^A versus σ_xx for various materials. The red shaded region in the figure represents the HoMn6Sn6 phase. The reported data for other materials are cited from literature.Figure S2. (a) The Lorentz TEM image of 360{degree sign} domain wall. The red solid line represents the theoretically contrast profile of the 360{degree sign} domain wall. The inset shows the experimentally measured contrast profile across the domain wall for comparison. (b) The Lorentz TEM image of 180{degree sign} domain wall.
