Energy and symmetry of dd excitations in undoped layered cuprates measured by Cu L-3 resonant inelastic x-ray scattering

Marco Grioni, Thorsten Schmitt, Helmuth Berger, Marco Guarise

We measured the high-resolution Cu L-3 edge resonant inelastic x-ray scattering (RIXS) of undoped cuprates La2CuO4, Sr2CuO2Cl2, CaCuO2 and NdBa2Cu3O6. The dominant spectral features were assigned to dd excitations and we extensively studied their polarizat ...
