Abstract
We examine the body of O-17 nuclear magnetic resonance (NMR) data obta ined in samples of YBa2Cu3O7-delta with T-c greater than or similar to 90 K. We point out significant deviations from typical metallic behav iour, contrary to conventional characterizations of these data. Furthe rmore, there is a surprisingly strong sample-to-sample variation in th e O-17 NMR properties, given the narrow range of oxygen content. We su ggest that this strong sample variability merits further study.
