Y89 NMR probe of Zn induced local moments in YBa2 ( Cu1−y Zny )3 O6+x

We report the observation of resolved $^{89}\mathrm{Y}$ NMR lines due to Zn nearest neighbors (nn) in ${\mathrm{YBa}}_{2}$(${\mathrm{Cu}}_{1\mathrm{\ensuremath{-}}\mathit{y}}$${\mathrm{Zn}}_{\mathit{y}}$${)}_{3}$${\mathrm{O}}_{6.64}$. Comparison of the Curie dependence of their frequency shifts with... View More
