On the basis of the interacting hole-spin model previously proposed, the temperature dependence of the longitudinal relaxation rate R of Cu NMR is calculated for the normal state. The rate is shown to consist of two terms; R=R_KrmK+R_D. The term R_K represents Korringa-like relaxation with strong enhancement due to the presence of 3d localized spins, and R_D comes from the spin diffusion among localized 3d system. The latter is almost temperature independent. This result is in good agreement with recent experiments.
