Intrinsic spin-disordered ground state of the Ising garnet Ho3Ga5O12
Abstract
Motivated by predictions of a spin-ice state on the Ising garnet lattice, we have completed neutron-scattering experiments on single crystals of Ho3Ga5O12. Our results show that although the Ho3+ spins have Ising-type character with an easy-axis anisotropy, the low-temperature ground state has coexisting long-range- and short-range-ordered spins and is therefore not an ice state. Inelastic neutron-scattering measurements reveal the presence of …
