YBa2Cu3O7 is an s-wave superconductor

Muon spin rotation (mu+SR) data on a single-crystal of YBa2Cu3O7 (Tc{approximately equal to}91.3 K, DeltaTc < 0.5 K) are reported. After properly accounting for flux-pinning effects as functions of both field and temperature, we find the bulk ground state to be strong-coupled s-wave in character....

Zusammenfassung:Muon spin rotation (mu+SR) data on a single-crystal of YBa2Cu3O7 (Tc{approximately equal to}91.3 K, DeltaTc < 0.5 K) are reported. After properly accounting for flux-pinning effects as functions of both field and temperature, we find the bulk ground state to be strong-coupled s-wave in character. The probability that YBa2Cu3O7 is a bulk d-wave superconductor is less than 4X10-6.
