摘要：

We report on the observation of Cu-EPR signals in single crystalline material of YBa2Cu3O6+delta in the narrow oxygen concentration range 0.7 < delta < 0.9 and for temperatures 80 K < T < 200 K. We provide evidence that the signal results from , Cu2+ ions located in ...Cu(1)...O...Cu (1)... chain fragments.
