Popis: We report 63Cu(2) spin-lattice relaxation rate measurements of YBa2Cu3O6.95 in magnetic fields from 2.1 to 27.3 T obtained from 17O(2,3) nuclear magnetic resonance spin-spin relaxation. For T < 120 K, the spin-lattice rate increases with increasing magnetic field. We identify this magnetic field dependence with the change in the low-energy spectral weight originating from d-wave pairing fluctuation corrections to the density of states. [S0031-9007(99)08771-2].
