Abstract

We have observed low-frequency excitations of spin-wave Brillouin scattering in ultrathin Co/Au(1 1 1) films with a large perpendicular magnetic anisotropy. With several monolayers (ML) of Co, we observe diffuse scattering under an external field just below a critical field at which the magnetization starts to incline toward out-of-plane. With Co films thicker than 6 ML, we find a new mode at fields lower than the critical field, in addition to a surface spin wave.
