Abstract

We have developed a combinatorial in situ growth-and-analysis system combining thin film growths by laser molecular beam epitaxy (MBE) with synchrotron radiation photoemission spectroscopy and X-ray absorption spectroscopy to investigate electronic structures of strongly correlated oxide systems, especially La1-xSrxMnO3 (LSMO) for tunneling magnetoresistance device applications. For combinatorial high-throughput analysis, we have developed a computer-controlled manipulator. The usefulness of combinatorial in situ analysis was verified by resonant photoemission and angle-resolved photoemission spectroscopy of Mn 3d e g derived majority band of compositional spread LSMO with various Sr compositions and thickness-dependent core-level shifts reflecting band bending.
