A composition-spread approach to investigate band-filling dependence on magnetic and electronic phases for Perovskite manganite

As-grown epitaxial composition-spread thin films of a colossal magnetoresistive compound, La1−xSrxMnO3 (0≤x≤1), are fabricated by a combinatorial laser molecular beam epitaxy (laser MBE). High throughput characterization for studying x dependencies of structural, magnetic and electronic properties is demonstrated by the combination of a concurrent X-ray diffractometer, a scanning superconducting quantum interference device (SQUID) microscope and an infrared microscope spectrometer, respectively.
