Orbital polarization of the Ni-3d orbital by oxygen coordination control. a Polarization dependent X-ray absorption spectroscopy (XAS) of Ni L2 edge for a S7/L1 and b S3/L1 superlattices. Large linear dichroism (LD) is observed for the S7/L1 SL, whereas the LD is nearly zero for the S3/L1 SL. Schematics of the eg orbital configuration are shown for c S7/L1 and d S3/L1 superlattices
