63'65Cu NMR and NQR studies of YBa2Cu307\_ b are described for compositions, 6, of 0.0, 0.3, and 0.9. Spin-lattice relaxation rates in YBazCu307 reveal significantly different electron dynamics at the two Cu sites in both the normal and superconducting states. In YBa2Cu306.7, the relaxation rates of
The superconducting property of YBa2(CUl\_xHx)307 {H=Zn and Ni) has been investigated by 63Cu NQR and NMR techniques. In case of Zn(3d I0) doped into CuO 2, the residual spin Knight shift of 63Cu increases appreciably with increasing concentration. Correspondingly,TIT=const. law holds far below Tc,
