Abstract

Y2C3 is a superconductor whose Tc changes from 6 to 18K depending on the synthesis conditions. Since its electronic properties were unknown, we performed the electrical-property study by measuring the microwave complex surface impedance, Zs, of Y2C 3 for different Tc's (13.9 and 15.5 K), and the resistivity and mean free path were determined in the normal state. We observed the typical behavior of a Drude metal in the Hagen-Rubens limit (ρ1 ≫ ρ2) in the normal state. We succeeded in observing the occurrence of superconductivity in the electrical property. Furthermore, we found that Y2C3 is a clean superconductor.
