X-ray Photoelectron Diffraction of Perovskite Oxides — •Mathias Glaser, Christoph Raisch, and Thomas Chassé — Universität Tübingen, Institut für Physikalische und Theoretische Chemie, Auf der Morgenstelle 8

Thin films of doped lanthanum manganites like La_0.7Ca_0.3MnO₃ (LCMO) show a distinctive colossal magneto resistance. In this work we report on x-ray photoelectron diffraction (XPD) measurements of LCMO films (grown by pulsed laser deposition) and of SrTiO₃ (STO). The presented polar scans were measured in [100]- and [110]-direction in both cases. In the case of STO the measured polar scans are typical of a cubic crystal structure. In comparison to that the polar scans of LCMO indicate a strained structure.
