Abstract
Bordelon et al. explore here the magnetic properties of the layered triangular lattice compound KCeO${}_{2}$. This material is a member of a family of rare earth based delafossite-like compounds, some of which were recently reported to harbor intrinsically quantum disordered ground states. The authors show that the Ce ions decorating this lattice type instead realize a weak low-temperature antiferromagnetic ground state, presenting a strong contrast to the spin liquid states formed by their Yb-based counterparts.
