Abstract

We performed the first electrical property study by measuring microwave complex surface impedance, Zs, of Y2C3 with Tc = 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.
