摘要: The Tb2Ti2O7 pyrochlore magnetic material is attracting much attention for its spin liquid state, failing to develop long-range order down 50 mK despite a Curie-Weiss temperature thetaCW approximately -14 K. In this Letter we reinvestigate the theoretical description of by considering quantum model independent tetrahedra describe low-temperature properties. naturally tuned proximity system near Neel ice phase boundary allows resurgence fluctuation effects that lead an important renormalization effective low-energy Hamiltonian. As result, argued be ice. We put forward experimental test proposal using neutron scattering on single crystal.
