Pseudo-easy-axis anisotropy in antiferromagnetic $S=1$ diamond-lattice systems Ni$X_2$(pym)${}_2$

S. Vaidya, A. Hernández-Melián, J. P. Tidey +12

We investigate the magnetic properties of $S=1$ antiferromagnetic diamond lattice, Ni$X_2$(pyrimidine)${}_2$ ($X$ = Cl, Br), hosting a single-ion anisotropy (SIA) orientation whi…
