Abstract
Spin-wave resonance (SWR) is a newly emerged method for studying surface magnetic anisotropy and surface spin-wave modes in (Ga,Mn)As thin films. On the basis of recent SWR studies of (Ga,Mn)As thin films we show that the cubic surface anisotropy is an essential factor determining the configuration regions of existence of surface spin-wave modes. These proved to exist only for those directions of film magnetization that lie in the immediate vicinity of hard cubic anisotropy axes.
