Chinese Physics B
Based on density functional theory calculations, the electronic and magnetic properties of Co-doped SnO are investigated. It is found that the spin-polarized state, with a magnetic moment of about 1.0 µ B per Co-dopant, is more favorable in energy than the non-spin-polarized state. Moreover, the origin of the ferromagnetism in Co-doped SnO is found to be the double exchange mechanism. Our results indicate that Co-doped SnO is a possible candidate of the p-type spintronics material.doi:10.1088/1674-1056/20/5/057101 fatcat:z4hdpfyngrdgnlsmw4pyjn2lwe
