摘要

Epitaxial Mn_3O_4/La_(0.7)Sr_(0.3)MnO_3 (Mn_3O_4/LSMO) bilayer thin films were grown on single crystal SrTiO_3 (STO) (100) substrates, with Mn_3O_4 as the top layer, using pulsed laser deposition technique. X-ray diffraction revealed the single crystalline nature and epitaxial relationship between the layers, as well as increased lattice distortion of LSMO in the bilayer structure relative to a single layer film of LSMO. Cross-sectional high resolution transmission electron microscope images showed atomically sharp interfaces, but in contrast to the almost flat interface between LSMO and STO substrate, the Mn_3O_4 and LSMO interface showed a zig-zag structure. Magnetic measurements indicated that the high temperature in situ deposition of a Mn_3O_4 layer on top of the LSMO film significantly reduced the magnetization of the LSMO film, probably due to the formed ziz-zag interface between LSMO and Mn_3O_4.
