Abstract: | This paper presents the synthesis and characterization of three new Y-based high temperature-superconducting compounds having relatively higher transition temperature T c compared with that of the Y-123, Y-124, and Y-247. The electrical resistivity measurements indicate the onset critical temperatures as high as 98 K. Atomic compositions of these new Y-Ba-Cu-O superconductors are Y2Ba3Cu5.2O x , Y2Ba5Cu9O x , and YBa4Cu5O x . The X-ray analysis has shown that they have a similar crystalline structure as Y-123 phases. |
