Interfacial properties of LaMnO3/LaNiO3 superlattices grown along (001) and (111) orientations

We have employed x-ray absorption spectroscopy and x-ray magnetic circular dichroism (XMCD) at the Ni andMn L-3,L-2 edges in LaMnO3/LaNiO3 superlattices grown along (001) and (111) orientations. Our results show a significant XMCD signal and thus the presence of magnetic moments localized on both Ni and Mn, which are ferromagnetically coupled to each other. X-ray absorption experiments reveal a charge transfer between Ni and Mn which is larger for (111) than for (001) superlattices. These results are compared to theoretical predictions for such superlattices.
