摘要：

We use a one-component description to analyze the current experimental situation for the low-frequency magnetic properties of La1.85Sr0.15CuO4 as determined by NMR and neutron-scattering experiments. We show that the measured O17 spin-lattice relaxation rate is in sharp conflict with the incommensurate-magnetic-structure interpretation of neutron-scattering experiments, but is quantitatively explained if the local-spin-fluctuation spectrum (measured by NMR) possesses a commensurate peak. We conclude that the formation of domains, as suggested by Slichter and Phillips, represents the best (and, quite possibly, only) way of reconciling NMR and neutron-scattering experiments on La1.85Sr0.15CuO4. © 1994 The American Physical Society.
