摘要：

Muon spin rotation (mu(+)SR) data on a single-crystal of YBa2Cu3O7 (T-c approximate to 91.3 K, DeltaT(c) < 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 4 x 10(-6). (C) 2004 Published by Elsevier B.V.
