Abstract
New superconducting cuprates in the Ca-doped Pr-123 system, have been synth esized successfully under high pressure. The compounds crystallize with tet ragonal structure. Electrical resistivity and magnetic susceptibility measu rements indicate superconductivity with transition temperatures as high as 115K. This indicates that carrier-doping and an appropriate synthesis route can effectively induce superconductivity in the Pr-123 system.
