| Abstract: | The technique of Green's function is used to investigate the surface spin waves in semiinfinite anisotropic Heisenberg magnet with a single-ion uniaxial anisotropy. The dispersion relations of surface excitations are obtained for the ferromagnetic, antiferromagnetic and ferrimagnetic systems, respectively. Results in some particular cases are discussed. |
