Short range order in the quantum XXZ honeycomb lattice material BaCo${}_2$(PO${}_4$)${}_2$

H. S. Nair, J. M. Brown, E. Coldren +5

We present observations of highly frustrated quasi two-dimensional (2D) magnetic correlations in the honeycomb lattice layers of the S${}_{eff}$ = 1/2 compound $\gamma$-BaCo${}_2$(PO${}_4$)$_…
