摘要
Magnetization and susceptibility studies on single crystals of the pyrochlore Ho2Ti2O7 are reported. Magnetization isotherms are shown to be qualitatively similar to that predicted by the nearest-neighbor spin-ice model. Below the lock-in temperature, T*similar or equal to1.97 K, magnetization is consistent with the locking of spins along [111] directions in a specific two-spins-in, two-spins-out arrangement. Below T* the magnetization for B parallel to [111] displays a two step behavior signaling the breaking of the ice rules.
