Singlet ground state probed by crystal field inelastic neutron spectroscopy on the antiferroquadrupolar system TmGa_{3}

M. G. Banks, R. K. Kremer, G. Lapertot +2

TmGa${}_3$ (AuCu${}_3$ structure) undergoes two phase transitions, an antiferroquadrupolar transition at $\sim$ 4.29 K and long-range antiferromagnetic ordering at $\sim$ 4.26 K. Due…
