✦ Synopsis
The spin-lattice relaxation rate in YBa2Cu307 is strongly affected by gap anisotropy. A model for this anisotropy is presented which accounts for the lack of Til enhancement just below T e as is expected from BCS theory. In addition, phonon induced quasiparticle damping is shown to contribute significantly to the relaxation rate, contrary to the case of conventional superconductors.
