Abstract
A manganese oxide thin film is formed on a plane of a substrate and has a composition RMnO, where R is at least one and preferably two trivalent rare earth elements selected from lanthanoids, and where both R and Mn form the same atomic layer parallel to the plane of the substrate. An oxide laminate, includes the manganese oxide thin film; and at least one strongly-correlated oxide thin film that is contiguous to the manganese oxide thin film, wherein a total thickness, t, of the oxide laminate, a thickness, tm, of the manganese oxide thin film, and a thickness, t, of the strongly-correlated oxide thin film satisfy a relation, relative to a critical thickness, tc, by which the strongly-correlated oxide thin film has a metallic phase, as follows: t=tm+t>tc and t<tc. Switching capabilities are ensured by a room temperature (Mott) phase transition.
