# Collinear ordering of easy-axis triangular lattice antiferromagnets - Condensed Matter > Strongly Correlated Electrons

Abstract: Antiferromagnetically coupled moments on the frustrated triangular latticetypically order in a coplanar state at low temperature. Here, we demonstratethat the presence of not-very-large easy axis single ion anisotropy leads to aninteresting orientationally ordered collinear state in triangular latticeantiferromagnets with moments $S \ge 3-2$. This ordered state breaks thesymmetry of $\pi-3$ rotations about a lattice site, while leaving intact thetranslational symmetry of the lattice.
