Abstract

We have studied on the crystalline and magnetic properties of ferromagnetic GaMnAs and nitrogen doped GaMnNAs films by plasma-assisted molecular beam epitaxy (p-MBE). The Curie temperature (Tc) of GaMnNAs increased slightly in a range of low nitrogen content compared to GaMnAs and showed the saturation with increase of Mn content. We have also investigated an annealing effect to the Tc.
