摘要
The influence of a nonmagnetic metallic substrate on the spin-wave excitations in ultrathin ferromagnetic overlayers is investigated for different crystalline orientations. We show that spin-wave damping in these systems occurs due to the tunneling of holes from the substrate into the overlayer, and that the spin-wave energies may be considerably affected by the exchange coupling mediated by the substrate.
