It was found that the local magnetic moments are localized mainly on the N dopant, causing a total moment of 0.95μB per cell. The long-range magnetic coupling of N-doped SnO2 may be attributed to a p-p coupling interaction between the N impurity and host valence states.||Funding Details:||Science Foundation Ireland
