Abstract

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