Abstract

Ru M $_3$ -edge resonant inelastic x-ray scattering (RIXS) measurements of RuCl $_3$ with 27 meV resolution reveals a spin-orbit exciton without noticeable splitting. We extract values for the spin-orbit coupling constant ( $\lambda=154\pm2$ meV) and trigonal distortion field energy ( $\left|\Delta\right|<65$ meV) which support the $j_{\rm eff}=1/2$ nature of RuCl $_3$ . We demonstrate the feasibility of M-edge RIXS for $4d$ systems, which allows ultra high-resolution RIXS of $4d$ systems until instrumentation for L-edge RIXS improves.
