Fig. 2
X-ray absorption spectroscopy (XAS) and X-ray magnetic circular dichroism (XMCD) spectra obtained at Ni and Cu L-edges in total electron yield mode without an applied electric field. The spectra for NiCu/BaTiO3 were measured in the normal incident geometry. a XAS results with differently polarized X-rays σ+ (red) and σ− (blue). b XMCD result obtained from the difference of the σ+ and σ− XAS spectra
