摘要
Recent progress in oxide perovskite thin-film technology has led to the discovery of a large negative magnetoresistance at room temperature in doped manganate perovskite thin films. These films may have potentials for magnetic sensing applications. In this paper we review the basic phenomena and physics of magnetotransport in this class of materials. We also discuss our recent demonstration of a large low-field magnetoresistance effect, and the associated challenges that lie ahead.
