We present numerical studies of dipolar spin ice in the presence of a magnetic field slightly tilted away from the [111] axis. We find a first-order transition from a kagome ice to a q =X state when the external field is tilted toward the [112] direction. This is consistent with the anomalous critical scattering previously observed in the neutron scattering experiment on the spin ice material Ho2Ti2O7 in a tilted field [Nat. Phys. 3, 566 (2007)]. We show that this ordering originates from the antiferromagnetic alignment of spin chains on the kagome planes. The residual entropy of the kagome ice is fully recovered. Our result captures the features observed in the experiments and points to the importance of the dipolar interaction in determining ordered states in the spin ice materials. We place our results in the context of recent susceptibility measurements on Dy 2 Ti2O7, showing two features for a [111] field.The magnetic degrees of freedom in spin ice materials [1,2], like the protons in their molecular counterpart, do not order at low temperature. The low energy sector is characterized by an extensive, narrow band of states [3,4] which can be treated as a vacuum for quasi-particle excitations carrying effective magnetic charge -magnetic monopoles [5,6]. The monopole model is derived from the dipole spin ice Hamiltonian (DSI) [7] and together they have enjoyed considerable success in describing both the static [5,8,9] and dynamic [10][11][12] properties of spin ice materials, Ho 2 Ti 2 O 7 (HTO) and Dy 2 Ti 2 O 7 (DTO), down to around 0.7 K. Below this temperature, slow dynamics [13-15] makes precision measurement difficult, so that life inside the band of low energy states remains mysterious.The states of the low energy band satisfy ice rules, where two spin point in and two out of each tetrahedral unit of the pyrochlore lattice (see Fig. 1). The narrowness of the band is a consequence of the high symmetry of the pyrochlore lattice, as the long range part of the dipolar interaction is screened [7,16] in the constrained states. A finite band width must therefore come from corrections to this projective equivalence [16] from higher order multipoles, or from other perturbations. The band of states contains the same Pauling entropy, S = (k B /2) ln(3/2) per spin, as the protons in water ice [4] and specific heat [3] and neutron scattering measurements [17] show that spin ice materials approach a correlated, disordered regime in which the Pauling entropy is retained, as the temperature is reduced below 1 K. Using the simplest DSI Hamiltonian, one finds that the degeneracy is lifted in zero external field in favor of an ordered state with the system undergoing a first order phase transition at 180 mK [18]. More sophisticated models with further neighbor exchanges modify this temperature [19], while external fields put the model system into different or-[111] [ 1 12] [111] FIG. 1.
