To investigate the properties of iron-based superconductors, we examined different kinds of Josephson junctions using Co-doped Ba-122 thin films. Based on bicrystalline SrTiO3 substrates, we prepared grain boundary (GB) junctions, which showed clear Josephson effects. We present electrical measurements at varying temperatures and magnetic fields. Furthermore, we prepared hybrid junctions using a thin-film technique. Confined by a Ba-122 base electrode (S) and a PbIn counter electrode (S'), two different geometries of hybrid junctions are formed, i.e., a planar SNS' junction with a gold barrier (N) in between and an edge-type junction with an interface-engineered barrier. All three kinds of junctions showed asymmetric resistively shunted junction-like behavior with ICRN products of 20.2 μV (GB junctions), 18.4 μV (planar SNS' junctions), and 12.3 μV (edge-type junctions), respectively. An excess current could be observed at all junctions.
