 note = {We studied the hole concentration dependences of ⁶³Cu Knight shifts in single-CuO₂-layer high-Tc cuprate superconductors HgBa₂CuO₄₊_δ and double-layer HgBa₂CaCu₂O₆₊_δ. We found that the spin Knight shift at room temperature as a function of the hole concentration in the single-layer superconductor is different from that in the double-layer superconductor. Two type relations between the spin Knight shift and the hole doping level serve to estimate the individual hole concentrations of the non-equivalent CuO₂ planes in a unit cell.},
