Abstract

The ⁶³Cu NMR spin-lattice relaxation rate of YBa₂Cu₃O_6.98 (T_C=93.3K) at the plane site shows classic Korringa temperature dependence in the normal state with T₁T=230±20 Kms. This resuit is consistent with Fermi quasi-particle character of the low lying electronic excitations near the Fermi energy. Precursory behavior is observed just above T_c in the relaxation data. This may be consistent with order parameter fluctuations.
