$\alpha$-RuCl3: a Spin-Orbit Assisted Mott Insulator on a Honeycomb Lattice

K. W. Plumb, J. P. Clancy, L. Sandilands +5

We examine the role of spin-orbit coupling in the electronic structure of $\alpha$-RuCl3, in which Ru ions in 4d5 configuration form a honeycomb lattice. The measured optical spectra ex…
