Jorgensen (Argonne National Laboratory, Argonne, Ill.): "YBa2Cu3O7-d is the compound that pushed the record temperature for superconductivity from 35 K to 92 K. Shortly after its discovery, many researchers realized that the superconducting properties could be varied dramatically by changing the oxygen content. The composition c
