Abstract
Josephson critical current densities Jc between UBe13 and an s-wave superconductor have been investigated for UBe13−Cu−Nb and UBe13−Nb junctions. The result that Jc increases with decreasing temperatures below Tc of UBe13, together with conventional Shapiro steps, indicates that we have observed the Josephson effect related to the bulk superconductivity of UBe13, and not the so-called proximity-induced Josephson effect, which was reported for the point contact between UBe13 and Ta.
