Typical weak links, or SNS′ junctions, in which a normal metal separates a conventional superconductor and a heavy fermion superconductor were fabricated using Cu, Nb, and polycrystalline CeCu2.2Si2 and UBe13 and single crystalline UPt3, respectively. The structures were investigated for Josephson effect. The temperature dependence of the critical current which provides evidence of unconventional superconductivity was observed when UPt3 was used.
