Characterization of localized hole states in Pr_(1+x)Ba_(2-x)Cu_(3)O_(6+y) by nuclear magnetic resonance

M. W. Pieper, F. Wiekhorst, T. Wolf

We investigated the charge distribution in Pr_{1+x}Ba_{2-x}Cu_3O_{6+y}-crystals at liquid-He temperature by means of ^{63,65}Cu- and ^{141}Pr-NMR and NQR. The electric field gradie…
