Abstract: Inspired by the recent extensive investigations of the ground-state magnetic properties in the rare-earth based triangular lattice antiferromagnet YbMgGaO$_4$ and the related insulating oxide compounds, we have recently carried out the single-crystal growth of the rare-earth based triangular lattice intermetallic compounds REZn$_3$As$_3$ (RE=Ce, Nd, Pr). These materials are strongly frustrated two-dimensional antiferromagnets with the rare-earth ions forming triangular lattice layers. Our studies of the physical properties of the grown high-quality single-crystal samples, including X-ray diffraction, low-temperature heat capacity and magnetic susceptibility measurements etc., have suggested complex magnetic ground states for the studied compounds, likely due to the interplay between geometric frustration, Kondo coupling and RKKY interactions. Further investigations via neutron scattering have been planned.
