Abstract
We report spin-lattice relaxation rate measurements of in magnetic fields from 2.1 to 27.3 T obtained from nuclear magnetic resonance spin-spin relaxation. For , 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 -wave pairing fluctuation corrections to the density of states.
