Abstract
A direct determination of the relationship between and hole concentration p for is obtained by investigating the properties of the fully oxygen-deficient (δ≊1.0) compound for which p=x/2. Measurements of , the thermoelectric power S, and bond-valence sums calculated from neutron-diffraction refinements for various values of x and δ allow the full determination of the relations p=p(δ), =(p), and S=S(T,p) confirming that satisfies the same universal relations in these quantities as the other high- superconducting cuprates.
