Dependence of propagation loss of magnetostatic forward volume waves on device parameters
It is shown that for magnctostatic forward volume waves (MSFVW) the propagation loss depends on device parameters such as thickness of magnetic film, MSFVW wavelength, a static magnetic field, etc. The result suggests that when the film thickness is about a quarter of the wavelength and the effective internal field is comparable to or larger than the saturation magnetisation of the film, the propagation loss per wavelength is minimised. Experimental results were in good agreement with this theoretical prediction.
