抄録

We have proposed a T_c vs n relationship for multilayered high-T_c superconductors from the analysis of HgBa₂Ca_n−1Cu_nO_y grain-aligned samples containing n=6 to 16 phases. The sample showed a large and sharp superconducting transition at 105 K in its susceptibility vs temperature curve. This means that multilayered HgBa₂Ca_n−1Cu_nO_y can maintain a high T_c at least up to n≈16, otherwise many transitions would have been observed. It is generally believed that the highest T_c decreases with n for n≥4–5 for multilayered superconductors. We conclude that the highest T_c is almost constant above about n=5 if the factors reducing T_c, such as disorder, are eliminated for multilayered superconductors. This behavior can be explained using an inhomogeneous charge distribution model in multilayered cuprates.
