RIXS spectra showing the effect of the Mn–COO on the dd excitations of the interfacial Cu ions. Comparison of the RIXS spectra at 18 K with π-polarization and an energy of 930.6 eV of the incident light that are representative of the response of the interfacial Cu ions for the two trilayers with y = 0.2 and y = 0.4 and a YBCO/LCMO superlattice without an intrinsic Mn–COO. It shows that the p1 peak, due to the transition from dx2−y2 to d3z2−r2, is most pronounced for the y = 0.2 trilayer with the strongest Mn–COO
