Abstract:This thesis describes the structural and magnetic properties of epitaxial
La0.67Sr0.33MnO3 (LSMO) thin films and nanostructures on single crystalline substrates. As LSMO is a half-metallic ferromagnet with almost 100% spin polarization and high curie temperature (TC = 360 K), a detailed analysis of different properties of LSMO thin films and nanostructures is essential in realizing magnetic devices based on this material. For the direct measurement of strain state and magnetic anisotropy of this material, it is necessary to grow LSMO thin films on different substrates which have different lattice mismatch with the film. As future spintronic devices ultimately have to be fabricated at nanoscale lateral dimensions, it is also important to study the magnetic properties of nanostructures of LSMO.
