Variation of skyrmion arrangement with temperature and T – B magnetic phase diagram of the 300-nm FeGe nanostripe. (a) Temperature dependence of skyrmion arrangements obtained as magnetic field is applied. (b) The magnetic phase diagram in the temperature and magnetic field plane. H, DSC, CPS, EV stand for helical state, distorted skyrmion chain, closely packed skyrmions and edge vortex structure, respectively. The colored dots show the experimental points, from which the phase boundaries are extrapolated as dotted lines to guide the eyes.
