| 中文摘要 | Using high-vacuum annealing treatment, the superconducting transition temperature T-c of the electron-doped Pr0.88LaCe0.12CuO4 +/-delta single crystals was successfully driven to a regime in which the T-c value continuously decreases with oxygen removal. This regime of oxygen-reduction process is hard to be understood according to the previous knowledge of this material. In addition, a remarkable relaxation of T-c over time was observed at room temperature, indicating that the variation in T-c is closely related to the rearrangement of oxygen in the sample. In combination with previous studies, it can be concluded that, in the whole process of oxygen reduction applied on Pr0.88LaCe0.12CuO4 +/-delta, although the strength of antiferromagnetic (fluctuation) correlations does play a role, T-c is dominated by the disorder effect of CuO2 plane either on copper sites or oxygen sites, which leads to a strong depairing effect. |
