The important role of Mn3+ in the room-temperature ferromagnetism of Mn-doped GaN films

Mn-doped GaN films (Ga1-xMnxN) were grown on sapphire (0 0 0 1) using Laser assisted Molecular Beam Epitaxy (LMBE). High-quality nanocrystalline Ga1-xMnxN films with different Mn concentration were then obtained by thermal annealing treatment for 30 min in the ammonia atmosphere. Mn ions were incorp...
