Abstract:
The magnetic and electronic properties of ferromagnetic undoped and N-doped TiO2−x rutile have
been probed by soft x-ray spectroscopies. Upon N doping, a fivefold enhancement of the saturation
magnetization is observed. Apparently, this enhancement is not related to an increase in oxygen
vacancies, rather to additional in-gap states, arising from the replacement of O with N atoms in the
rutile structure that can provide more favorable conditions for the onset of ferromagnetic
ordering
