Abstract

The Josephson effect was studied in heavy-fermion superconductor CeTIn5. For CeCoIn5, Josephson critical current Ic was observed just below superconducting transition temperature. For CeIrIn5, the temperature below which Ic appeared varied from junction to junction and Ic increased gradually reflecting a distribution of the local transition temperature.
