A narrow symmetrical line with a g factor of 2.002 was detected in the ESR spectra of the materials. On the basis of analysis of the dependence of the line intensities on the heat treatment conditions it was concluded that the signal belongs to singly charged oxygen vacancies V(+)O \\\\Expert2\\nbo\\Theoretical and Experimental Chemistry\\2012, V.48, № 3, p.139.pdf |
