Abstract: The half-metallic ferromagnetic of Gallium nitride doped with double impuritiesGa1−2xMnxCoxN (x=3% and 6%) has been investigated by means of first principles investigation combined with Monte Carlo Simulation. The stability of the ferromagnetic state is investigated by comparing the total energies to the spin-glass state. The exchange interactions obtained from first principle calculations and used in a classical Ising model by a Monte Carlo approach resulted in half-metallic ferromagnetic states with high Neel temperature.
