Surface twist instabilities and skyrmion states in chiral ferromagnets
Surface twist instabilities and skyrmion states in chiral ferromagnets
In epitaxial MnSi/Si(111) films, the in-plane magnetization saturation is never reached due to the formation of specific surface chiral modulations with the propagation direction perpendicular to the film surfaces [Wilson et al., Phys. Rev. B 88, 214420 (2013)]. In this paper we show that the occurrence of such chiral surface …
