Neutron Scattering studies of a new Yb-based triangular lattice compound

In two-dimensional magnetic systems, the triangular lattice has long been an interesting topic due to its potential to host exotic ground states such as quantum spin liquid (QSL). However, most of the real-world compounds of this class process chemical disorders which makes the interpretation of the ground state difficult. We have grown the first single crystal of a new Yb-based triangular lattice compound without the chemical disorder. In this talk, we are going to present our latest results on this new compound including thermodynamics and neutron scattering measurements.
