摘要：

We report the observation of an EPR spectrum attributable to Cu2+-Cu2+ pairs with resultant electronic spin S = 1, from cupric oxide annealed in the temperature range from 700 to 900-degrees-C. The spectrum consists of only a single line at g = 3.12 with seven hyperfine components. From the weight loss and oxygen content measurements, it was found that the observation of such a signal strongly depends on the oxygen content of the sample.
