Resonant inelastic X-ray scattering investigation of Hund's and spin-orbit coupling in $5d^2$ double perovskites

Felix Ivo Frontini, Christopher J. S. Heath, Bo Yuan +8

B site ordered $5d^2$ double perovskites (${\mathrm{A}}_2\mathrm{B}{\mathrm{B}}^{\prime }{\mathrm{O}}_6,{\mathrm{B}}^{\prime }=5d^2)$ display a remarkable range of physical properties upon variation of the chosen B and ${\mathrm{B}}^{\prime }$ site io…
