Abstract:
1. A method of manufacturing a magnetoresistive element comprising a magnetoresistive film, wherein the method comprises forming a functional layer disposed at an interface between a lower magnetization pinned layer and an upper magnetization pinned layer, at an interface between a lower magnetization free layer and an upper magnetization free layer, at an interface between a magnetization pinned layer and an intermediate layer, at an interface between the intermediate layer and a magnetization free layer, at an interface between the magnetization pinned layer and a cap layer, or at an interface between the magnetization free layer and the cap layer, and providing a pair of electrodes which passes a current perpendicularly to a plane of the magnetoresistive film, wherein forming the functional layer includes: repeating consecutively two or more processes each comprising depositing a metal layer containing 5 atomic % or more of Fe and exposing the metal layer to a nitrogen atmosphere to form a nitride of an Fe-containing metal.
