Variations of spin texture with magnetic field in 396-nm FeGe nanostripe at T =100 K. (a) and (b) Magnetic-field dependence of the spin texture — the crystal boundaries in the right are marked by white dotted lines. (c) The region marked by the dotted white rectangle in corresponding panels (a) and (b) enlarged. The small white arrows stand for the in-plane magnetization direction at each point. The thick white arrows are plotted to guide the eyes.
