heal.abstractThin films grown by pulsed-laser deposition from Sn0.95Fe 0.05O2 were investigated. The M?ssbauer spectra of 57Fe show that iron was all high-spin Fe3+ but films were magnetically inhomogeneous on atomic scale with 23% of iron ordering magnetically. The ferromagnetic exchange mechanism which involved spin-polarized electron trapped at oxygen vacancy was also suggested. The ferromagnetic coupling of ferric ions via an electron trapped in bridiging oxygen vacancy was also proposed to explain high Curie temperature.en
