Isothermal magnetization of grain-aligned HgBa2Ca2Cu3O8 as a function of the applied magnetic field parallel to the c-axis was measured. The curves were analyzed by using the extended critical state model which includes the combined effects of the surface barrier and the magnetization due to pinning. It is shown that the effect of the surface barrier in this mercury-based superconductor is significant especially at the high-temperature region.
