Explaining the Magnetic Properties of Oxygen Deficient LSMO Thin Films by iDPC

The manganite family of perovskites are among the most promising materials in magnetoelectronics research due to their colossal magnetoresistance, room temperature ferromagnetism, and high curie temperature In thin films, however, a magnetic dead layer (MDL) arises, diminishing the magnetic properties in isolated regions The origin of the MDL has been widely studied in the context of oxygen vacancies or cation intermixing to accommodate for the interfacial polar discontinuity, strain due to lattice mismatch with the substrate, and electronic reconstruction by octahedral distortion or rotation. Currently no conclusion about the MDL origin is established, but there is evidence that the answer lies in the oxygen octahedral structure
