Abstract

The temperature dependence of Cu-NMR relaxation rate T₁^-1 and spectra have been measured for La-based high-T_c cuprate La_1.89Ca_1.11Cu₂O_6+δ with the bilayer type of CuO planes. The shift showed a monotonic decrease with lowering temperature in the normal state, showing that this compounds belongs to the lightly doped region. The Curie Weiss temperature dependence of (T₁T)^-1 down to T_c shows that the pseudo spin-gap does not always exist in the bilayer systems.
