Quantum structural diagrams and high-T sub c superconductivity.

Using golden coordinates we have successfully isolated superconductors with T sub c > 10K into three small volumes in elemental configuration space. Two volumes contain the familiar NbN and Nb sub 3 Ge materials, but the third volume contains both the Chevrel sulfide and Bednorz-Muller-Chu oxide materials. Compounds in the third volume with formulae near YBa sub 2 Cu sub 3 O sub 7 are suggested as promising candidates for new high-T sub c superconductors.
