Abstract
The authors report Cu NMR studies of YBa2Cu3O7−δ (Tc = 90K) in the normal state (using oriented single crystals) and superconducting state (using oriented powders). In the normal state they measure the electric field gradient tensor, the magnetic shift tensor, the spin-lattice relaxation tensor, and the time dependence of the transverse decay (spin-echo envelope) and draw conclusions about the charge and spin states of the Cu atoms. In the superconducting state they measure the shift tensor, using the 89Y resonance to measure the internal field in the sample. The data are compared with various detailed models of spin pairing.
