抄録

We performed the first electrical property study by measuring microwave complex surface impedance, Z_s, of Y₂C₃ with T_c = 15.5 K. First of all, the resistivity was determined successfully in the normal state. We observed a typical behavior of the Drude metal in the Hargen-Rubens limit (ρ₁ ≫ ρ₂) in the normal state, and we succeeded in observing the occurrence of superconductivity in the electrical property for the first time. We found that Y₂C₃ was a typical type-II clean superconductor.
