First-principles Study on Magnetism of Cu in GaN
Journal of Magnetics, Volume 14, Number 3, 30 Sep 2009, Pages 114-116
Abstract
The electronic properties of Cu or Pd-doped GaN at several concentrations are examined using the full-potential linear muffin-tin orbital method. For (Cu0.055Ga0.945)N, the model reveals a magnetic moment of 1.47μB per supercell. The range of concentrations that are spin-polarized should be restricted within narrow limits. A paramagnetic to ferromagnetic phase transition is found to occur at a Cu concentration of 5.55%.
