Double transition in calcium-123 (CaSr 2Cu 3O y) superconductor

The Ca 2+ is successfully substituted for the 3+ rare earth element in the 123 ceramic structure. A double phase transition is observed in oxygen deficient samples. A superconducting transition onset occurs at 90 K, and all resistivity vanishes at 73 K. However, at a lower temperature of 50 K the sa...
