摘要:

我们对铁基超导体BaFe_(1.8)Co_(0.2)As_2的角结进行了相敏测量,观察到了典型的类夫琅和费衍射花样。结果表明,铁基超导体的a-c面和b-c面之间没有相移,表明铁基超导体的超导波函数与铜氧化物超导体的超导波函数不同。

英文摘要:

We have made a phase-sensitive measurement on the corner junction of the iron-based superconductor BaFe1.8Co0.2As2, and observed the typical Fraunhofer-like diffraction pattern. The result suggests that there is no phase shift between the a-c face and b-c face of a crystal, which indicates that the superconducting wavefunction of the iron based superconductor is different from that of a cuprate superconductor.
