Probing the nematic insulator Tm<sub>1-x</sub>Y<sub>x</sub>VO<sub>4</sub> with neutron scattering near quantum criticality

ORAL

Abstract

The insulator TmVO4 have recently been established as a model system to study electronic nematicity near quantum criticality. The material undergoes a continuous ferroquadrupolar transition due to partially filled 4f orbitals of the Tm ions, mediated by long range interactions via the lattice. The transition can be described by the magnetic transverse field Ising model with a crossover to the nematic transverse field Ising model near the quantum critical region. Here we present results from neutron scattering on single crystal and powder samples of the system Tm1-xYxVO4 at various compositions in order to study the effects of disorder on electronic nematicity near a quantum critical point.
