Probing single magnon excitations in Sr${}_2$IrO${}_4$ using O $K$-edge resonant inelastic X-ray scattering

X. Liu, M. P. M. Dean, J. Liu +8

Resonant inelastic X-ray scattering (RIXS) at the $L$-edge of transition metal elements is now commonly used to probe single magnon excitations. Here we show that single magnon exc…
