Comparison of the NMR and neutron scattering experiments on cuprates with nonmagnetic impurities

Abstract

The NMR and neutron scattering experiments on YBa2Cu3O7 with U and Zn impurities are compared using a simple framework exhibiting short-range antiferomagnetic correlations. The model parameters are determined by fitting the NMR rate T-2(-1) of the pure system, and the effective impurity potential is approximated by a static extended form. The results of the calculations are compared with the experimental data, and their implications are discussed.
