Abstract
In a magnetoresistance multilayer film comprising at least two magnetic layers on a substrate, with a nonmagnetic layer intervening between the magnetic layers, each interface between the magnetic layer and the nonmagnetic layer is corrugated in both X and Y directions of a substrate major surface. The corrugations of the interface are formed by providing the substrate surface with a multiplicity of asperities distributed in both X and Y directions and depositing magnetic layers and nonmagnetic layers thereon. The film shows a linear rise of MR change in an applied magnetic field within a very low range of 0 to about 40 Oe.
