Description

The single-phase high-T/sub c/ superconductors YBa2Cu3O/sub 7-//sub x/S/sub x/ and YBa2Cu/sub 3(1-//sub y//sub )/Fe3/sub y/O7 have been prepared and studied by dc magnetometry. YBa2Cu3O6S has a larger unit cell than YBa2Cu3O7, and yet has the same T/sub c/; its phase transition is sharper and displays full Meissner effect. Substitution of Cu by Fe leads to a sharp decrease in T/sub c/
