Abstract
We report the experimental results on the reversible magnetization of the triple-layer compound B0.6C0.4(Sr0.25Ba0.75)2Ca2Cu3O9 with Tc≃119 K. In comparison with HgBa2Ca2Cu3O8+δ, which is the same triple-layer compound, this superconductor showed enhanced interlayer coupling due to relatively short interlayer spacing. This feature was reflected by the three-dimensional scaling behavior of the fluctuation-induced magnetization around Tc(H). On the other hand, the charge-carrier density calculated from the conventional theories was significantly smaller than the value on HgBa2Ca2Cu3O8+δ. The relatively large penetration depth λab(0)=214 nm of this superconductor might be due to the small carrier density. We conclude that the competition between enhanced interlayer coupling strength and reduced carrier density make the Tc of B0.6C0.4(Sr0.25Ba0.75)2Ca2Cu3O9 lower than that of HgBa2Ca2Cu3O8+δ.
