Resumen:
An attempt to produce massive magnetic semiconductors by doping TiO2 with 5 at% of Fe using the ball milling technique is presented here. Local environment surrounding magnetic impurity atoms in the partially reacted alloys have been investigated using Mossbauer spectroscopy. Results indicate that fully reacted samples cannot be achieved under the different experimental conditions tested and that the only resulting phase that displays magnetism at room temperature is the unreacted a-Fe.
