NMR study of supersolid phases in the triangular-lattice antiferromagnet Na2BaCo(PO4)2

Xiaoyu Xu, Zhanlong Wu, Ying Chen +10

We report ultra-low-temperature ${}^{23}$Na NMR measurements on the Ising triangular lattice antiferromagnet Na${}_2$BaCo(PO${}_4$)${}_2$, which precisely resolve the phase diagram under m…
