Epitaxial LSMO films grown on MgO single crystalline substrates

Effects of annealing on structure and composition of LSMO thin films

“…It indicates that the content of LSMO decreases and the content of LaMnO x increases. A polycrystalline film is observed on the surface of annealed LSMO film by cross-sectional transmission electron microscopy (TEM) [22]. It can be attributed to the LaMnO x nanocrystalls existed in the surface of annealed LSMO film in our studied.…”

“…observed Mn vacancies and Sr rich surface oxide after annealing in low pressure of O 2 and found that the surface layer was weakly affected by subsequent annealing. Spankova et al reported that a polycrystalline nanogranular region is detected on the surface of annealed LSMO film [22]. However, the evolution of structure and composition of LSMO thin films as a function of annealing has not been systematically investigated.…”

Microstructures and electrical properties of La0.8Sr0.2MnO3 films synthesized by sol–gel method

“…Moreover, another advantage is that the delamination between two layers is not found as described at last paragraph. Effect of the amount of powders on the sheet resistance can be explained by the decrease in micro-cracks and the increase in grain size, both of which may result in an easier transmission of the carriers [27].…”

Characterization of Electrical Transport in Lsmo with Enhanced Temperature of Metal-Insulator Transition

“…Structural and compositional analyses (Auger electron spectroscopy, X-ray diffraction, Transmission electron microscopy) indicate that the LSMO films are stoichiometric, single phase and epitaxial [3,4], in spite of some nonideal crystallographic matching of the LSMO film with the MgO substrate. The main attribute of the LSMO films -the enhanced T MI -we were able to prepare reproducibly.…”
