| 英文摘要 | Abstract we studied the grain boundaries within mechanically formed polycrystalline ba 0.6 k 0.4 fe2as2 micro-bridges. by tunneling current across grain boundaries, current–voltage characteristics (ivcs) demonstrated the typical josephson weak links behavior in micro-bridges. shapiro steps were observed for the junctions under the microwave radiation at 10 ghz. the temperature dependence of the critical current ic was observed as a shoulder, corresponding to a multi-gap symmetry but not a single-gap s-wave or d-wave. |
