St. Dai et Zy. Li, SPIN-WAVES IN A SEMIINFINITE HEISENBERG-FERROMAGNET WITH MAGNETOCRYSTALLINE ANISOTROPY, Communications in Theoretical Physics, 30(1), 1998, pp. 21-26
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.
