摘要: Abstract Perovskite cobaltates LaBaCo 2 O 5.5+ δ thin films were directly integrated onto (001) Si substrates by pulsed laser deposition. Microstructural studies from X-ray diffraction reveal that the are polycrystalline. Electrical transport property measurements indicate polycrystalline have a semiconductor behavior with largest magnetoresistance value of 18% at ~40 K. Magnetization show exhibit magnetic similar to its bulk materials nanoscale ordered 6 and larger moments coercive field than single-crystal films.
