Influence of the parameters of material onto surface spin wave refraction in two-axis ferromagnetic media
Refraction index is calculated for surface spin waves propagating in a ferromagnetic medium with inhomogeneous distribution of the parameters of exchange interaction, uniaxial and rhombic anisotropy. The coefficients of spin wave reflection and transmission are calculated at the boundary of two homogeneous magnetic materials with different constants of exchange interaction, uniaxial and rhombic anisotropy, as well as saturation magnetisation. The dependencies of reflection coefficient and refraction index on wave frequency and value of an external permanent homogeneous magnetic field are obtained.
