Abstract
A magnetoresistance-effect element includes a substrate, and a magnetoresistance-effect film disposed on the substrate. The magnetoresistance-effect film includes an alloy film containing ferromagnetic metal atoms and non-magnetic metal atoms, which have the property relative to each other that they are mutually insoluble in both solid and liquid phases. The magnetoresistance-effect film further includes at least three soft magnetic films arranged as discontinuous areas in contact with the alloy film and magnetically coupled therewith for reducing an operating magnetic field strength of the element.
