Abstract

The possibility of controlling the spin-waveguide modes of propagation of a strain signal in lateral arrays of a magnon-crystal structure with a piezoelectric layer is shown via Mandelstam–Brillouin spectroscopy of magnetic materials with spatial and frequency resolution. The possibility of controlling the dipole spin-wave coupling in a lateral array of ferromagnetic strips by creating local deformations in the region of localization of spin-wave excitations is demonstrated. It is shown that changing the absolute magnitude and sign of the electric field allows effective control over the properties of propagating spin waves and the spatial distribution of the intensity of dynamic magnetization in the lateral structure at frequencies in the spectrum of surface magnetostatic waves.

摘要

通过具有空间和频率分辨率的磁性材料的曼德尔施塔姆-布里渊光谱显示了控制应变信号在具有压电层的磁振子结构的横向阵列中传播的自旋波导模式的可能性。证明了通过在自旋波激发的局部区域中产生局部变形来控制铁磁条横向阵列中偶极自旋波耦合的可能性。结果表明，改变电场的绝对幅度和符号可以有效控制传播自旋波的特性，以及在表面静磁波频谱中的频率下横向结构中动态磁化强度的空间分布。
