Electron-induced stabilization of ferromagnetism in GaGdN
Gustavo M. Dalpian, Su-Huai Wei
Using {\it ab initio} band structure calculations and symmetry arguments, we show that the magnetic property of GaGdN is drastically different from TM-doped GaN. The co…

Band structure model of magnetic coupling in semiconductors
Gustavo M. Dalpian, Su-Huai Wei, X. G. Gong +2
We present a unified band structure model to explain magnetic ordering in Mn-doped semiconductors. This model is based on the - and - level repulsions between the Mn io…
