Abstract
The 89YNMR shift and relaxation have been measured as a function of temperature and composition in the YBa2Cu3O7- delta system. Values are deduced for N(EF)s and N(EF)d at the yttrium site. The authors find N(EF)s-1/atom and 0.13F)d-1/atom for YBa2Cu3O7 with lower values for N(EF)d as delta increases.Keywords
