Magnetic-field dependence of planar copper and oxygen spin-lattice relaxation rates in the superconducting state of YBa2Cu3O7.
J. A. Martindale,S. E. Barrett,K. E. O’Hara,Charles P. Slichter,Wei-Cheng Lee,D. M. Ginsberg +5 more
TL;DR: The authors report nuclear spin-lattice relaxation rates, [ital W][sub 1], for planar copper and oxygen sites in the superconducting state of YBa[sub 2]Cu[sub 3]O[sub 7], which give the zero-field limit necessary for comparison with theory.

Nuclear-spin-lattice relaxation-rate measurements in YBa2Cu3O7.
J. A. Martindale,S. E. Barrett,D. J. Durand,K. E. O’Hara,Charles P. Slichter,Wei-Cheng Lee,D. M. Ginsberg +6 more
TL;DR: The relaxation rate data are shown to be inconsistent with a spin-singlet, orbital [ital s]-wave pairing state with an isotropic energy gap.

NMR studies of the superconducting pairing state of YBa2Cu3O7
Charles P. Slichter,J. A. Martindale,S. E. Barrett,K. E. O’Hara,S. M. De Soto,Takashi Imai,D. J. Durand,Charles H. Pennington,T. A. Friedmann,W. C. Lee,D. M. Ginsberg +10 more
TL;DR: In this paper, the spin and orbital pairing of the superconductor YBa 2 Cu 3 O 7 has been investigated and it is shown that the NMR data in the superconducting state require a spin-singlet pairing state.

TL;DR: In this article, the authors review and up-date their work on Knight shifts, spin-lattice relaxation, and indirect nuclear spin-spin coupling for YBa2Cu3O7 in the superconducting state.

NMR in the superconducting state of YBa2Cu3O7
J. A. Martindale,S. E. Barrett,Christopher A. Klug,K. E. O’Hara,S. M. Desoto,Charles P. Slichter,T. A. Friedmann,D. M. Ginsberg +7 more
TL;DR: In this paper, the authors studied the 63 Cu spin-lattice relaxation times in YBa 2 Cu 3 O 7 below the superconducting transition and showed that the orbital pairing in this state is d-like, and that at low temperatures and strong fields the fluxoid cores may dominate the relaxation mechanism.
