Static and Dynamic Magnetic Properties of Single-Crystalline Yttrium Iron Garnet Films Epitaxially Grown on Three Garnet Substrates (vol 4, 1800106, 2018)

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 x 10(-3). The FV SW dispersion curve is calculated from the magnetic anisotropy and it shows good agreement with experimental data.
