Abstract
In order to understand the magnetostatic wave modes of a YIG thin film, grown by a liquid-phase epitaxy (LPE) method, the ferromagnetic resonance spectra were investigated. When the static magnetic field was parallel to the film plane, the MSSW modes and the MSBVW modes were observed. The magnetic properties of the sample showed a saturation magnetization of 136.7 emu/cc and a uniaxial magnetic anisotropy constant of 1800 erg/cc at room temperature. As the temperature decreased the resonance field positions of the MSSW modes and the MSBVW modes moved gradually to the low-field region. The saturation magnetization decreased gradually with increasing temperature in the range 133–473 K. The line width of the MSW mode decreased with decreasing temperature in the range 473–353 K, and was almost constant in the range 353–213 K. (© 2004 WILEY-VCH Verlag GmbH & Co. KGaA, Weinheim)
