Abstract
Rare-earth triangular-lattice materials naturally combine the effects of geometric frustration and strong spin-orbit coupling, providing an ideal platform for the search of novel phases. Here, the authors report a combination of insights from the low-temperature specific heat data and theoretical modeling that provide a near-precise identification of the CeCd${}_{3}$As${}_{3}$ magnetic ground state and a remarkable level of certainty regarding the part of the phase diagram where it belongs, paving the way to a deeper understanding of a broad class of materials.
