A minimum is found on the temperature dependence of the magnetic susceptibility of vanadium monoxide of different compositions at a temperature of about 700 K. X-ray diffraction analysis performed before and after measuring the magnetic susceptibility confirmed the change in the structure of vanadium monoxide and the possibility of atom–vacancy processes upon cooling and heating of the samples \\\\Expert2\\nbo\\Bulletin of the Russian Academy of Sciences Physics\\2007, V. 71, N 5, P. 677-680.pdf |
