摘要:
A new type of surface spin wave occurs in a ferromagnetic film with an applied magnetic fieldperpendicularto the surface when the dipole and exchange energies are comparable. The surface wave propagates parallel to the surface but has a wave vector whose normal component iscomplex. States having a high degree of localization of the spin wave amplitude near the surfaces can occur.
