Robust Ti4+ states in SrTiO3 layers of La0.6Sr0.4MnO3∕SrTiO3∕La0.6Sr0.4MnO3 junctions
We have investigated the interfacial electronic structure of La0.6Sr0.4MnO3 (LSMO)∕SrTiO3 (STO)/LSMO heterojunctions utilizing the elemental selectivity of photoemission spectroscopy. The Ti 2p core-level spectra clearly show Ti4+ states and do not exhibit any indication of Ti3+ states in TiO2 layers irrespective of a different kind of adjacent atomic layer with …
