$A\phantom{\rule{0}{0ex}}R$O${}_{2}$ ($A$=alkali, $R$=rare earth) compounds are well known for forming layered triangular lattices, but they also form other structures. One of these is a three-dimensional tetragonal form chosen by LiYbO${}_{2}$, which is experimentally and theoretically explored in this paper. An unusual spiral magnetic state forms, reflective of frustration inherent to the stretched diamond network of Yb ions. This is modeled by a Heisenberg model, which further predicts a…
