Figure 1: Schematic diagram of the artificial skyrmion lattices and measured magnetic hysteresis loops.

From: Realization of ground-state artificial skyrmion lattices at room temperature

Figure 1

(a) The hybrid structure consists of Co dots (red) on top of Co/Pd PMA underlayer (grey) where the in-plane spin texture of the Co dots (purple arrows) is imprinted into an irradiated Co/Pd region (light blue) underneath the dots (tilted blue arrows). Green and yellow arrows indicate the moments in the Co/Pd underlayer and the core region of the (imprinted) vortex, respectively. Major in-plane (open symbols) and perpendicular (solid symbols) hysteresis loops are shown for (b) the Co/Pd underlayer as grown, (c) the irradiated Co/Pd witness sample and (d) the hybrid Co+Co/Pd sample.
