Sapphire single crystals were implanted at room temperature with 180 keV manganese ions to fluences up to 1.8 β’ 10 17 cm Γ2 . The samples were annealed at 1000 Β°C in oxidizing or reducing atmosphere. Surface damage was observed after implantation of low fluences, the amorphous phase being observed a
