Resonant inelastic X-ray scattering study of spin-wave excitations in the cuprate parent compound Ca${}_2$CuO${}_2$Cl${}_2$

B. W. Lebert, M. P. M. Dean, A. Nicolaou +10

By means of resonant inelastic x-ray scattering at the Cu L${}_3$ edge, we measured the spin wave dispersion along $⟨$100$⟩$ and $⟨$110$⟩$ in the undoped cupr…
