Influence of an inclined anisotropy on formation of spatially inhomogeneous phase in two‐dimensional ferromagnet

Abstract

Phase states of ultrathin magnetic film with an inclined anisotropy are investigated. It is shown, that in a 2D film with easy-axis, easy-plane anisotropies, and inclined out-of-plane anisotropy the realization of spatially inhomogeneous phase is possible only at specific orientation of an external magnetic field. If orthorhombic anisotropy is implemented in the film plane, then the spatially inhomogeneous phase realizes at arbitrary orientation of in-plane external field.

Dynamic and static properties of rigidly fixed ultrathin ferromagnetic films with S = 1 and competing anisotropies

“…(23), (24), (28), and (29)) and the quadrupole phase (Eqs. (40) and (41)) and depends on the relationship among the single-ion anisotropy constants, as well as on the orientation of the wave vector.…”

“…[24][25][26][27][28] The systems described above have been studied fairly well for the case of small single-ion anisotropy constants. 29,30 However, there is a large class of magnetically ordered systems in which the single-ion anisotropy energy is quite large. The existence of a large easy-plane anisotropy in a system leads to a number of effects of a purely quantum mechanical nature and cannot be explained in terms of phenomenological models.…”

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

“…The tilted anisotropy energy is the weakest compared to other types of interaction (we consider here weakly disoriented magnetic structures netodipole interaction, which can lead to the forma tion of spatially inhomogeneous phase states [16][17][18][19]. The spin of the magnetic ion will be set as unity.…”
