Fig. 1: RSXMS, spin structure and complex dielectric susceptibility in HOSG-QDs/La1.8Ba0.2CuO4/LaAlO3.

a The spin structures in HOSG-QDs/La1.93Ba0.07CuO4/LaAlO3 showing the in-plane and out-of-plane spin-polarizations. b Resonant soft X-ray and magnetic scattering were measured at three different energies showing the scattering geometry and the valence spectroscopies involving these three transition energies. Complex dielectric susceptibility at c O K edge and d Cu L3,2 edges.
