Compass-model physics on the hyperhoneycomb lattice in the extreme spin-orbit regime.

ABSTRACT: The physics of spin-orbit entangled magnetic moments of 4d and 5d transition metal ions on a honeycomb lattice has been much explored in the search for unconventional magnetic orders or quantum spin liquids expected for compass spin models, where different bonds in the lattice favour different orientations for the magnetic moments. Realising such physics with rare-earth ions is a promising route to achieve exotic ground states in the extreme spin-orbit limit; however, this regime has remained experimentally largely unexplored due to major challenges in materials synthesis. Here we report the successful synthesis of powders and single crystals of β-Na₂PrO₃, with 4f¹ Pr⁴⁺ j_eff = 1/2 magnetic moments arranged on a hyperhoneycomb lattice w
