Impact of the lattice on magnetic properties and possible spin nematicity in the S=1 triangular antiferromagnet NiGa${}_2$S${}_4$

Michael E. Valentine, Tomoya Higo, Yusuke Nambu +5

NiGa${}_2$S${}_4$ is a triangular lattice S=1 system with strong two-dimensionality of the lattice, actively discussed as a candidate to host spin-nematic order brought about by strong…
