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.
