Abstract

The oxygen content effects on the superconducting transition temperature in the HgBa₂Ca_n-1Cu_nO_2n+2+δ(n=1-5) have been analyzed systematically in terms of the bond valence sums. The parabolic correlation between the T_c and Cu valence is observed for the single, double and triple CuO₂ layer materials. Inhomogeneous charge distribution in the two types of CuO₂ planes is found when n≥3. The nonmonotonic dependence of the maximum T_c on n is investigated on the basis of both the total mobile hole concentration in the octahedral or pyramidal CuO₂ planes at the optimal level and the generalized Lawrence-Doniach theory.
