Magnetoresistance and conductivity in the binary system titanium–oxygen. II. Semiconductive Titanium Oxides

In continuation of the investigations of the electrical and thermal conductivity as well as the magneto resistance in the binary system titanium-oxygen for TiOx with metallic conductivity for x < 1.49 the corresponding properties for the semiconductive compounds with 1.49 < x < 2 are measured at low temperatures and magnetic inductions up to 15 T, especially the corundum phase Ti2O3, the Magnéli phase Ti4O7 and the reduced rutil phase TiO2−ϵ in dependence on oxygen content and temperature.
