Resumen:
Samples of Sn0.90Fe0.10O2 were prepared by mechanosynthesis method.The structure and magnetic behavior of the samples have been investigated byX-ray diffraction (XRD) and Mössbauer spectroscopy. It has been found that forshort milling times a small percentage of the initial hematite remains simultaneouslywith the formation of metallic Fe. Additionally a paramagnetic contribution appearsin the Mössbauer spectra. For milling times, over 2 h, the iron ions are in paramagneticstates having +3 and +2 oxidation states while by XRD only the rutile structurediffraction lines were observed.
