英文摘要: A series of nano CoO-AlOx granular films were prepared by Ar-O-2 reactive rf sputtering and their resistive and magnetoresistive proper-ties were measured for studying the spin-dependent properties. Transmission electron microscopy and X-ray photoelectron spectroscopy are also utilized to investigate the structures and chemical states of these samples. Based on our results, the particles of CoO with radius around 2 nm could be magnetic at room temperature and provide a large tunneling magnetoreststance of - 6% through the AlOx barrier.
