Abstract

Williams and Krämer [Phys. Rev. B 64, 104506 (2001)] have recently argued against the existence of staggered magnetic moments residing on several lattice sites around Zn impurities in YBa2Cu4O8 superconductors. This claim, which is in line with an earlier publication by Williams, Tallon, and Dupree [Phys. Rev. B, 61, 4319 (2000)], is, however, in contradiction with a large body of experimental data from different nuclear magnetic resonance (NMR) groups. On the contrary, the authors argue in favor of a very localized spin and charge density on Cu sites that are first neighbors to Zn. We show that the conclusions of Williams and Krämer arise from erroneous interpretations of NMR and nuclear quadrupole resonance data.
