Abstract
New superconducting cuprates of (M,C)(Sr,Ba)(2)Ca2Cu3O9 (M=Al and Ga) family have been synthesized under high-pressure. We have found that p artial substitution of Ba2+ for Sr2+ and/or that of C4+ for M3+ in MSr 2Ca2Cu3O9 (M=Al and Ga) are effective to improve homogeneity and to en hance the Tc.
