Abstract
The magnetic behavior of lanthanum manganite thin films (LaMnO₃) deposited on strontium titanate (SrTiO₃) was explored as a function of manganese oxidation state, as controlled by the presence of cation and oxygen vacancies. This was done in response to the inconsistent magnetic properties found in literature. The films were characterized using Rutherford backscattering spectroscopy, wide-angle x-ray diffraction, x-ray reflectivity and vibrating sample magnetometry. The films were found to exhibit an antiferromagnetic to ferromagnetic transition consistent with that found in strontium-doped LaMnO₃ systems, where the manganese oxidation state is controlled by the fraction of strontium present.
