Abstract
Magnetization and susceptibility studies on single crystals of the pyrochlo re Ho2Ti2O7 are reported. Magnetization isotherms are shown to be qualitati vely similar to that predicted by the nearest-neighbor spin-ice model. Belo w the lock-in temperature, T*similar or equal to1.97 K, magnetization is co nsistent with the locking of spins along [111] directions in a specific two -spins-in, two-spins-out arrangement. Below T* the magnetization for B para llel to [111] displays a two step behavior signaling the breaking of the ic e rules.
