| Abstract: | The system V1?xFexO2 (x ? 0.020) was investigated by X-ray diffraction, DTA, magnetic susceptibility measurements and Mössbauer spectroscopy. The phase diagram and the magnetic properties are similar to those of the V1?xCrxO2 and V1?xAlxO2 systems previously studied. In oxygen deficient materials appears a Magnéli type shear phase, the Fe3+ ions occupying the shear planes. |
