Excitations in new disorder-induced quantum spin ice Ho2(Ti0.9Hf0.1)2O7
Ho2Ti2O7 is the prototypical spin ice, but lacks sizeable quantum dynamics. Following a theoretical study, we propose to investigate possible disorder-induced Quantum Spin Liquids. In this quantum spin ices, low-energy excitations are expected, which is in stark contrast with their classical counterparts. In Ho2(Ti0.9Hf0.1)2O7, our experimental observations corroborate the persistence of spin ice correlations along with strengthened fluctuations due to disorder-induced transverse fields. We propose to measure the excitations in a Ho2(Ti0.9Hf0.1)2O7 single crystal. This experiment would thus provide a clear demonstration of a QSI in a material based on a large dipole moment and where, therefore, the signatures will be easier to track than in typical QSI candidates based on small moments such as Pr3+ compounds.
