Using a bare impurity potential which is onsite and attractive, magnetic and single-particle properties have been calculated. The QMC results show that giant oscillations develop in the Knight shift response around the impurity site due to the short-range antiferromagnetic correlations. These results are useful for interpreting the NMR data on Li- and Zn-substituted layered cuprates.pdfPhysicsJournal Article1550-235Xhttps://doi.org/10.1103/PhysRevB.68.235103188186400030Q2NOIR00766
