The revisited theoretical phase diagrams for thin films of cubic helimagnetswith the easy-plane anisotropy are shown to have different topology aspreviously reported [Phys. Rev. B 85, 094429 (2012)]. For both in-plane andout-of-plane directions of an applied magnetic field, the phase diagramsexhibit extensive areas of stable skyrmions, which overlap for a wide range ofanisotropy parameters. Although the existence of the out-of-plane skyrmions wascontradicted within the previous theoretical models, we prove that additionalsurface twists lead to their stability, while the moderate easy-planeanisotropy increases the stability range of in-plane skyrmions. Moreover, theinterplay between the anisotropy and the surface twists gives rise to a stablespiral state canted with respect to the surfaces. Being absent in bulkhelimagnets, this oblique spiral occupies vast areas at the phase diagrams inthin-film nanosystems and serves as a connecting-link between cones andhelicoids. Our theory gives clear directions for renewed experimental studiesof in-plane and out-of-plane skyrmions in epitaxial MnSi(111)/Si(111) thinfilms.

Stability of in-plane and out-of-plane chiral skyrmions in epitaxial MnSi(111)/Si(111) thin films: surface twists versus easy-plane anisotropy
