Magnetic Ni-N-Ni Centers in N-substituted NiO

Author(s): Simon Godin, Ilya S. Elfimov, Fengmiao Li, Bruce A. Davidson, Ronny Sutarto, Jonathan D. Denlinger, Liu Hao Tjeng, George A. Sawatzky, and Ke Zou To explore how anion substitution modifies the existing magnetism in strongly correlated oxides, we investigate local electronic states and magnetic ordering in nickel oxide (NiO) induced by substituting oxygen (O) with nitrogen (N). Each N introduces an additional N $2p$ hole and modifies the magne… [Phys. Rev. Lett. 135, 046706] Published Thu Jul 24, 2025
