The indirect spin–spin interaction through the field of virtual phonons polarized in the plane of incidence in a magnetic layer with slip boundaries in an unbounded nonmagnetic medium can lead to the appearance of bound states of magnon polarons in the continuous spectrum of radiative bulk Lamb magnetoacoustic modes. If a longitudinal plane bulk elastic wave is incident on this layer from outside, this mechanism ensures both the formation of magnetoacoustic Fano resonance and its collapse, as well as the implementation of the acoustic superradiance effect for a finite system of equidistant magnetic layers. The incidence of a quasiplane longitudinal wave can be accompanied by a sharp enhancement of the angular Shoch effect.

层状磁结构纵向声子共振散射中的量纲磁声效应

通过在无界非磁性介质中具有滑移边界的磁性层中的入射平面极化的虚声子场的间接自旋-自旋相互作用可导致在辐射体兰姆磁声的连续光谱中出现磁振子极化子的束缚态模式。如果纵向平面体弹性波从外部入射到该层,该机制确保了磁声法诺共振的形成及其坍塌,以及等距磁层的有限系统的声学超辐射效应的实现。准平面纵波的入射可以伴随角肖赫效应的急剧增强。
