摘要: 以57Fe作为探针,用穆斯堡尔效应研究YBa2Cu3O7-δ的磁有序与超导电性的关系。实验结果可以用非声子超导机制进行定性解释。
Abstract: The relation between magnetic ordering and superconductivity of YBa2Cu3O7-δ was studied by M?ssbauer effect with 57Fe as probe in Cu lattice. The experimental results can be under-stood qualitatively by non-phonon superconductivity mechanism.
