Density functional theory description of the mechanism of ferromagnetism in nitrogen-doped SnO2

Long, Run ; English, Niall J. (Elsevier, 2009-12-28)

Based on first-principles calculations, we have studied the occurrence of spin polarization in the magnetic metal oxide SnO2 doped with nonmagnetic nitrogen (N) impurities. It was found that the local magnetic moments are ...
Magnetic properties of first-row element-doped ZnS semiconductors : a density functional theory investigation

Long, Run ; English, Niall J. (American Physical Society, 2009-09-22)

Based on first-principles calculations, we have investigated the magnetic properties of the first-row element-doped ZnS semiconductors. Calculations reveal that Be, B, and C dopants can induce magnetic, while N cannot lead ...
