Abstract:
The crystalline structure and composition of a GaMnSb film is studied. The film is produced on a GaAs (100) substrate by deposition from laser plasma in a hydrogen flux at a temperature of 400$^\circ$C. The formation of GaMn inclusions in the GaSb:Mn matrix is detected. The stoichiometry ratio of the inclusions corresponds to that of the Ga$_{162.5}$Mn$_{101.5}$ compound.
