Abstract
The Knight shift and the nuclear magnetic relaxation rates W⊥63, W∥63, and W∥17 are calculated for temperatures below the superconducting transition temperature of the high-temperature cuprate superconductors; the superscripts refer to the Cu63 and the O17 nuclei while the subscripts refer to the direction of the magnetic field with respect to the CuO layers. The calculations are based on a recently proposed interlayer tunneling mechanism of superconductivity in these materials. In general, the results are consistent with experiments even though the superconducting gap respects the full point-group symmetry of the lattice (anisotropic s wave); the anisotropy of the magnitude of the gap is an essential element.
