Investigation of the dynamic Kagome ice emerged from a field along [1, 1, 1] in Nd2Hf2O7.

Abstract: Pyrochlore compounds are considered to have an ideal crystal structure for 3D geometrical frustration, resulting in novel ground states. Spin ice, is one of the most striking ground states, with monopole- like excitations. Classical spin ice can be melted by quantum fluctuations introduced by non- Ising terms in the magnetic Hamiltonian. We have synthesized a high quality single crystal of Nd2Hf2O7 and performed successfully inelastic neutron scattering measurements in zero field. We solved the magnetic Hamiltonian with a model that classifies it as proximate to quantum spin ice with a dynamical pinch point mode. There are indications that a dynamic kagome ice state can emerge by applying field along the cube diagonal ([1,1,1] direction). Here we wish to explore this new state by applying fields along the [1,1,1].
