 note = {Magnetism of Gadolinium-doped gallium nitride (GaGdN) depending on the Ga flux during crystal growth is investigated using magnetic Doppler broadening (MDB) measurements and M-H measurements. In Ga deficient condition, the matrix phase of  GaGdN layer is regarded as  GaN due to the precipitation of  GdN nanoparticles.  From the MDB measurements, magnetic moments at gallium vacancies (V Ga ) in GaN is detected, however, ferromagnetism derived from GdN nanoparticle is dominant. In Ga rich condition, pure GaGdN layer was formed and weak ferromagnetism was observed. The MDB measurements detect the magnetic moments at V Ga  in GaGdN, hich might be a source of magnetism.},
