Single‐crystalline yttrium iron garnet (YIG) films are grown on gadolinium gallium garnet (GGG), rare‐earth‐substituted GGG, and neodymium gallium garnet (NGG) substrates, and their crystalline structures, surface morphologies, magnetic and magneto‐optical properties, spin wave (SW) spectra of the forward volume (FV) mode, and damping parameters are characterized. YIG grown on NGG shows the smallest out‐of‐plane effective anisotropy field of 1080 Oe among the three samples because of its larger magnetoelastic anisotropy contribution, and its damping parameter is 1.1 × 10⁻³. The FV SW dispersion curve is calculated from the magnetic anisotropy and it shows good agreement with experimental data.

在三个石榴石衬底上外延生长的单晶钇铁石榴石薄膜的静态和动态磁性能

单晶钇铁石榴石（YIG）膜在g镓镓石榴石（GGG），稀土取代GGG和钕镓镓石榴石（NGG）衬底上生长，并且其晶体结构，表面形态，磁和磁光性质，前向体积（FV）模式的自旋波（SW）光谱和阻尼参数进行了表征。在NGG上生长的YIG表现出三个样品中最小的面外有效各向异性场1080 Oe，这是因为它的磁弹性各向异性贡献更大，其阻尼参数为1.1×10 ^-3。FV SW色散曲线是根据磁各向异性计算得出的，与实验数据显示出很好的一致性。
