Two-dimensional honeycomb lattices of magnetic ions with strong spin-orbit coupling can host a rich variety of magnetic phases, including Kitaev quantum spin liquids. Here, Okuma et al succeeded in synthesising powders and single crystals of β-Na2PrO3, with Praseodymium ions with very strong spin-orbit coupling arranged in a three-dimensional hyperhoneycomb lattice.
