Figure 4

A micromagnetic simulation of a single 0.6 nm Co layer film with interfacial DMI showing the (a) Mx and (b) Mz components of magnetisation. (c) Resulting simulated Fresnel image with beam tilt of 45°, tilt axis indicated in green. (d–f) show experimental Fresnel images of N = 10× ML sample taken at different sample tilt +30°, 0° and −30° respectively. The tilt axis is as indicated by the arrow.
