Abstract:
1. A magnetoresistance effect element comprising: a pinned layer of a ferromagnet with a fixed magnetization direction; a magnetic recording layer of a ferromagnet with a thin wire shape including a region with a variable magnetization direction; and a non-magnetic layer with a thin wire shape formed between the pinned layer and the magnetic recording layer, wherein: the magnetic recording layer includes three regions consisting of pinned magnetization regions at the ends and a magnetization switching region sandwiched therebetween; the pinned layer and the pinned magnetization regions include current supply terminals; and at least one of the pinned layer and the magnetic recording layer is formed from a ferromagnet enabling a magnetization direction to be changed from parallel to perpendicular to a film plane by controlling a film thickness to be not more than 3 nm, with a controlled magnetoresistance ratio and with the magnetization direction perpendicularly oriented with respect to the film plane by a film thickness control.
