Effect of tilted anisotropy on spin states of strongly anisotropic 2D film

Abstract

The spin states of a 2D film with a strong easy plane anisotropy and single ion tilted anisotropy, the axis of which forms a certain angle with the normal to the film plane are investigated. In this system, an angular ferromagnetic phase, a spatially inhomogeneous state, and a quadrupole phase can be formed; the realization of these states noticeably depends on the degree of tilted anisotropy.
