Magnetization plateaus and sublattice ordering in easy axis Kagome lattice antiferromagnets

Arnab Sen, Kedar Damle, Ashvin Vishwanath

We study kagome lattice antiferromagnets where the effects of easy axis single-ion anisotropy ( $D$ ) dominates over the Heisenberg exchange $J$ . For $S \geq 3/2$ , virtual quantum flu…
