Resumen:
A sample of 10at%Fe-dopedSnO2 powder was prepared by mechanical alloying and then thermally treated at 773K in vacuum. The fit of the diffraction patterns and X-ray absorption spectroscopy measurements revealed that the as milled sample was pure doped rutile. Fe dissolved into SnO2 was found in Fe2+/Fe3+ ionic valence with mainly paramagnetic behavior. After the thermal treatment all techniques indicate the formation of the ternary Sn0.36Fe2.64O4 spinel phase,which is responsible for the observed ferromagnetism.
