Abstract

A hidden order that emerges in the frustrated pyrochlore Tb2+xTi2-xO7+y with X = 0.005 > xc is studied from specific heat and magnetization experiments on a high-quality single crystal, as well as neutron scattering. Semi-quantitative3 analyses based on a pseudospin-1/2 pyrochlore Hamiltonian for ionic non-Kramers magnetic doublets indicate that it is a long-range of an electric quadrupole. These results suggest the existence for a Higgs phase located close to a U(1) quantum spin-liquid phase of the non-Kramers pyrochlore model.
