Abstract
Green function formalism is employed to investigate the effect of magn etocrystalline anisotropy on surface spin waves in semi-infinite Heise nberg ferromagnets at low temperatures T much less than T-c. The dispe rsion relations are investigated in detail. The density of states (DOS ) of surface spin waves and layered magnetizations are also derived.
