N2 - We have studied the magnetic hysteresis and relaxation processes of grain-aligned HgBa2CuO4, HgBa2CaCu2O6, and HgBa2Ca2Cu3O8 compounds. The penetration field, Hp, the width of the magnetization loops, M, and the irreversibility field, Hirr, of each compound were found to exhibit an exponential temperature dependence [i.e., Hp, Hirr, M exp(-cT/T0)]. This suggests that their magnetic relaxation is controlled by the penetration of two-dimensional pancake vortices over the Bean-Livingston surface barrier.
