摘要：

Neutron polarisation analysis and zero field +mu-SR have been used to search for localised atomic moments in YBa2(Cu0.96Zn0.04)3O7. The PA measurements indicate that there are fewer than 1.5% Cu atoms carrying a spin of 1/2. The muon relaxation function is consistent with that due to static nuclear dipoles. Although the relaxation rate exhibits an unusual temperature dependence below T(c), there is no strong evidence for either static or fluctuating local atomic spins.
