Reorientation phase transition in temperature in a two- and three-dimensional ferromagnet with the account of magnetoelastic coupling

The reorientation temperature in ultrathin ferromagnetic films

“…[8], Fridman et al investigated reorientation phase transition in a two-dimensional ferromagnet. It was shown that the inclusion of magnetoelastic coupling results in the appearance of an angular phase, and the phase transitions are of the first order.…”

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

“…The account of this quite weak interaction is essential. The ME coupling leads to both dynamic effects (the hybridization of elastic and magnetic excitations, which is shown in "softening" of quasiacoustic wave in the vicinity of orientation phase transitions) and static effects (the formation of a striction gap in the spectrum of magnetic excitations) [6,9]. We suppose, that ME interaction is two-dimensional, i.e.…”

Influence of Dipole Interaction on the Phase Transitions Due to Temperature Variation in Two-Dimensional Ferromagnets

“…Nowadays great interest is evoked by the investigation of ultrathin films [1][2][3][4][5][6][7][8][9][10]. First of all, it is related to the fact that such objects can be used in microelectronics, e.g.…”

“…A great number of experimental [1,3] and theoretical [5][6][7][8][9][10] works is devoted to the investigation of this effect. In [1,5,7] it was shown that the process of magnetization ''switching" from the out-of-plane phase to the in-plane one occurs due to the competition between the one-site ''easy-axis" anisotropy and dipole interaction creating an effective anisotropy of the ''easy-plane" type.…”

“…However, in Refs. [9,10] another mechanism responsible for phase transitions of such kind was proposed. This mechanism is based on the model that takes into account the magnetoelastic (ME) coupling and phenomenological temperature dependence of the one-site anisotropy.…”
