Abstract

Data on the Cu63 nuclear-magnetic-resonance intensity in powdered ceramic samples of YBa2Cu3O7 are analyzed to yield the relative and absolute intensities of the Cu(1) and Cu(2) sites, using similar data on Cu63 in Cu2O as a reference standard. These data confirm the assignment of the 31.48 MHz nuclear-quadrupole-resonance line to the Cu(2) (planar) sites and the 22.05 MHz line to the Cu(1) (chain) sites mandated by recent experiments at other laboratories. Relaxation data for Y89, also presented, may reflect antiferromagnetically correlated spin fluctuations in the planes.
