%X We report vibrating coil magnetometry of the spin-ice system Ho2Ti2O7 down to 0:04 K for magnetic fields up to 5 T applied parallel to the [111] axis. History-dependent behavior emerges below T0 0:6 K near zero magnetic field, in common with other spin-ice compounds. In large magnetic fields, we observe a magnetization plateau followed by a hysteretic metamagnetic transition. The temperature dependence of the coercive fields as well as the susceptibility calculated from the magnetization identify the metamagnetic transition as a line of first order transitions terminating in a critical end point at Tm' 0:37 K, Bm’ 1:5 T. The metamagnetic transition in Ho2Ti2O7 is strongly reminiscent of that observed in Dy2Ti2O7, suggestive of a general feature of the spin ices.
