Abstract

A phase diagram of the dynamic magnetoelastic states of an easy-plane antiferromagnet is constructed. A dispersion relation is obtained for nonlinear magnetoelastic eigenwaves. It is shown that, at the point of the orientational phase transition, the dispersion of coupled spin and elastic waves depends only on wave amplitudes and parameters of magnetoelastic coupling.

定向相变附近磁性有序晶体中的非线性弹性波

摘要

构造了易平面反铁磁体的动态磁弹性状态的相图。获得非线性磁弹性本征波的色散关系。结果表明，在取向相变点，耦合的自旋波和弹性波的色散仅取决于波幅和磁弹性耦合的参数。
