Abstract

We have measured the reversible magnetization M(H, T) for grain-aligned HgBa₂Ca₂Cu₃O_8+δ. Our data exhibit a clear vortex fluctuation about 6 K below the superconducting onset temperature. The derived in-plane magnetic penetration depth λ_ab(0) is 1700 Å which is similar to those of other high-T_c superconductors. In addition, the zero-temperature GL coherence length ξ_ab (0) is 22±5 Å, which implies GL parameter κ{script}=77±13. This κ{script} is much greater than that of HgBa₂CuO₆, but similar to that of YBa₂Cu₃O₇.
