Combining micro- and macroscopic probes to untangle single-ion and spatial exchange anisotropies in a $S=1$ quantum antiferromagnet

Jamie Brambleby, Jamie L. Manson, Paul A. Goddard +14

The magnetic ground state of the quasi-one-dimensional spin-1 antiferromagnetic chain is sensitive to the relative sizes of the single-ion anisotropy ($D$) and the intrachain ($J$)…
