Thermodynamics and neutron scattering studies of on a new Tm-based triangular lattice system

Motivated by the recent discovery of the quantum spin liquid (QSL) candidate material YbMgGaO4 and possible Kosterlitz-Thouless (KT) phase in TmMgGaO4, we successfully synthesized the Tm-based triangular lattice sister compound. The key characteristic of this compound is that compared to the previously proposed QSL candidates, it has a more two-dimensional magnetic structure in which the role of chemical disorder is minimized. Our thermodynamics measurements measured down to 50 mK rule out any signature of long-range magnetic ordering in this system. Furthermore, we employed neutron scattering techniques to probe the static and dynamic magnetic properties of this system.
