Abstract
Doping the high- superconductor with of nonmagnetic Zn impurities in planes is shown to produce a considerable broadening of NMR spectra, as well as an increase of low-energy magnetic fluctuations detected in spin-lattice relaxation measurements. A model-independent analysis demonstrates that these effects are due to the development of staggered magnetic moments on many Cu sites around each Zn and that the Zn-induced moment in the bulk susceptibility might be explained by this staggered magnetization. Several implications of these enhanced antiferromagnetic correlations are discussed.
