Abstract

The Mn 3d spectral function in La_0.6Sr_0.4FeO ₃(LSFO)/La_0.6Sr _0.4MnO₃ (LSMO) heterointerfaces using Mn 2p-3d resonant photoemission spectroscopy was investigated. The Mn 3d spectra of LSMO layers in the surrounding of the interface with the LSFO overlayers was extracted with the strong enhancemnt of Mn 3d spectra at Mn 2p-3d threshold. It was found that the spectral intensity of e_g↑ states near the Fermi level was reduced with increasing LSFO overlayer thickness. It was stated that reduction of states between the LSFO/LSMO interface and hole-doped LSMO films lead to the occurence of charge transfer at the interface between the LSMO and LSFO layers.
