Abstract

Data are presented for the magnetic susceptibility of YBa2Cu3O7 and for the anisotropy of the copper nuclear spin-lattice relaxation time T1 in the normal state for planar [Cu(2)] sites in this system. Using the Cu NMR shift to partition the susceptibility and estimate the density of states, we analyze the conventional enhanced Korringa model of T1 contributions, finding it incapable of accounting for the anisotropy of the observed relaxation times. A localized spin-fluctuation picture is also discussed briefly.
