Valence band ARPES study of La1-xSrxMnO3 single crystals
(2004) 9th International Conference on Electronic Spectroscopy and Structure 137-40. p.499-503- Abstract
- We have observed a feature at similar to2.5 eV binding energy (BE) in the valence band of La1-xSrxMnO3 single crystals not previously reported in the literature. The relative intensity of this feature decreases with increasing Sr concentration x and has a strong photon energy dependence. It also exhibits a complicated angle dependence. In this report we present a full set of angular-resolved photoemission spectra performed on (100) La1-xSrxMnO3 single crystals. The shape of the valence band has a strong dependence on emission and incident angles. In particular, at hupsilon = 130 eV the intensity of the 2.5 eV BE feature increases when the emission angle changes from 0 to 20degrees, and then sharply drops. The shape of the valence band...

The shape of the valence band changes with incident angle as well, and the feature is more pronounced at larger incident angles. A strong dependences on Sr doping as well as photon energy is also established. (C) 2004 Elsevier B.V. All rights reserved. (Less)
