|Issue Date:||1-Apr-2011||Citation:||Bao, N.N., Fan, H.M., Ding, J., Yi, J.B. (2011-04-01). Room temperature ferromagnetism in N-doped rutile TiO2 films. Journal of Applied Physics 109 (7) : -. ScholarBank@NUS Repository. https://doi.org/10.1063/1.3535427||Abstract:||Room temperature ferromagnetism has been experimentally observed in TiO2:N films prepared by pulse laser deposition under N2O atmosphere. The ferromagnetism appears when the N2O partial pressure is higher than 10-5 Torr. XPS study has revealed that N substitutes O at the partial pressure of 10-5 Torr, whereas additional N atoms occupy interstitial sites besides substituting N at higher N2O partial pressures. Our study indicates that the origin of the ferromagnetism is the O substitution with N. Each substituted N has a magnetic moment of approximately 0.9 B. The substitution of O also resulted in p-type behavior, accompanied with magnetoresistance and anomalous Hall effect. © 2011 American Institute of Physics.||Source Title:||Journal of Applied Physics||URI:||http://scholarbank.nus.edu.sg/handle/10635/86954||ISSN:||00218979||DOI:||10.1063/1.3535427|
