摘要：

The authors review evidence, from NMR of Cu-63 and O-17 atoms in the CuO planes, concerning the spin and orbital pairing of the superconductor YBa2Cu3O7. It shows that the NMR data in the superconducting state require, a spin-singlet pairing state. It is consistent with orbital d-wave pairing, but not with a conventional orbital s-wave pairing. Whether or not other types of orbital pairing states (e.g. anisotropic s-state) can explain the data can only be judged when those theories are used to calculate the NMR properties.
