Ligand-SOC enhanced $4f^5$ Kitaev antiferromagnet: Application to ${\mathrm{SmI}}_3$

Li-Hao Xia, Yi-Peng Gao, Zhao-Yang Dong +1

The search for Kitaev quantum spin liquids (Kitaev-QSLs) in real materials has mainly focused on $4d$- and $5d$-electron honeycomb systems. A recent experimental study on the $4f^5…
