Evidence for Dynamic Phase Separation and High Energy Spin Dynamics in underdoped La${}_{2-x}$Sr${}_x$CuO${}_4$ from Resonant Inelastic X-Ray Scattering

L. Braicovich, J. van den Brink, V. Bisogni +7

We probe the collective magnetic modes of La${}_2$CuO${}_4$ (LCO) and underdoped La${}_{2-x}$Sr${}_x$CuO${}_4$ (LSCO) by momentum resolved Resonant Inelastic X-ray Scattering (RIXS) at the C…
