Magnetic nature of the 500 meV peak in $\mathrm{L}{\mathrm{a}}_{2-\mathrm{x}}\mathrm{S}{\mathrm{r}}_{\mathrm{x}}\mathrm{Cu}{\mathrm{O}}_4$ observed with resonant inelastic x-ray scattering at the Cu $K$-edge

D. S. Ellis, Jungho Kim, J. P. Hill +9

We present a comprehensive study of the temperature and doping dependence of the 500 meV peak observed at $\mathbf{q}=(\pi ,0)$ in resonant inelastic x-ray scattering (RIXS) experiments…
