The electrical conductivity and magnetoresistance of amorphous Si films implanted by Mn ions up to a concentration of 22 at% are investigated near the metal–insulator transition (MIT). We find that there is a characteristic temperature TSG = 6 to 20 K (dependent on the Mn concentration) which separa...
