Measurements of the static paramagnetic susceptibility chi p and magnetisation M have been performed on p-type manganese-doped GaAs. Pronounced deviations from a pure Curie-type(chi sub p) or Brillouin-type (M) behaviour were observed. These can be assigned to a low-lying energy level at about 2.5 meV resulting from exchange coupling of the delocalised hole with the 3d E5 manganese acceptor core. (IAF)
