Abstract

Perovskite cobaltates LaBaCo₂O_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 LaBaCo ₂O_5.5+δ films are polycrystalline. Electrical transport property measurements indicate that the polycrystalline LaBaCo ₂O_5.5+δ films have a semiconductor behavior with a largest magnetoresistance value of 18% at ~40 K. Magnetization property measurements show that the polycrystalline films exhibit magnetic behavior similar to its bulk materials of nanoscale ordered LaBaCo₂O ₆ and have larger magnetic moments and magnetic coercive field than the single-crystal LaBaCo₂O_5.5+δ films.
