Collective spin excitations in a quantum spin ladder probed by high-resolution Resonant Inelastic X-ray Scattering

J. Schlappa, T. Schmitt, F. Vernay +13

We investigate magnetic excitations in the spin-ladder compound Sr${}_{14}$Cu${}_{24}$O${}_{41}$ using high-resolution Cu $L_3$-edge Resonant Inelastic X-ray Scattering (RIXS). Our findi…
