N2 - We have measured the reversible magnetization M(H, T) for grain-aligned HgBa2Ca2Cu3O8+δ. Our data exhibit a clear vortex fluctuation about 6 K below the superconducting onset temperature. The derived in-plane magnetic penetration depth λab(0) is 1700 Å which is similar to those of other high-Tc superconductors. In addition, the zero-temperature GL coherence length ξab (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.
