Abstract
We observed the pseudo spin-gap behavior in the T-dependences of 63Cu Knight shift and NMR relaxation rates, as well as electrical resistivity, over a wide doping range for the bilayer high-Tc HgBa2CaCu2O6+δ using 63Cu NMR spin-echo technique. We found a difference in the doping dependence of the pseudo spin-gap behavior between HgBa2CaCu2O6+δ and the previous monolayer HgBa2CuO4+δ. The results indicate that the pseudo spin-gap behavior strongly depends on the underlying electronic states.
