Abstract
The article considers the results of vanadium dioxide VO2±X study (within the homogeneity range) and solid solutions V1-XFeXO2, obtained by X-ray diffraction and the Faraday method. The temperature dependences of the magnetic susceptibility samples are presented, and it follows that dependence χ (T) character in the temperature range from 100 К up to 250 К is close to Curie law for paramagnetic in the area of the phase transition at temperature Tmp ∼ 340 К, and there is an abrupt change in χ. It is considered that the magnetic properties of vanadium dioxide vary both with the change in the oxygen content in the samples and with the doping of vanadium dioxide with iron. It was established that vanadium dioxide VO2±X and solid solutions V1-XFeXO2 are paramagnetic both in the semiconductor and metallic states.
