Abstract

A new "1222"-type compound containing carbonates, (C_0.35Cu_0.65)Sr₂(Y_0.73Ce_0.27)₂Cu₂O_x, was synthesized at 1303 K under an atmosphere of O₂ (80%)-CO₂ (20%) (partial pressure of CO₂: PCO₂=0.020 MPa). The sample annealed at 1023 K under the high oxygen pressure of 90 MPa has a superconducting transition temperature, T_c, of 18 K and a superconducting volume fraction of about 10% at 5 K. The structure of the superconductor was analyzed using the Rietveld method for the X-ray powder diffraction pattern. The refined lattice parameters were a=3.8272(1), b=3.8313(1) and c=27.7077(6) A ̊.
