Interface-Dependent Magnetotransport Properties of Perovskite Lanthanum Manganite Thin Films

Enhanced functionalities and/or emergent behavior, often not accessible from the individual constituents, could be produced by interfacing certain materials at different length scales. Over the years, major advances have been made to synthesize high crystallinity epitaxial perovskite lanthanum manganite films with controlled microstructures and to gain a fundamental understanding of their physical properties. In this talk, we will discuss our strategies in the synthesis and characterization of epitaxial lanthanum manganite films. Using perovskite lanthanum manganite as the model system, we examine interface-dependent magnetotransport properties by creating both vertically aligned nanocomposite films and layered heterostructures. Specifically, we will discuss the effect of interfaces (both vertical and lateral interfaces) on the magentotranport properties of lanthanum manganite films.
