    摘要: A magnetoresistance effect element includes a magnetoresistance effect film including a magnetically pinned layer having a magnetic material film whose direction of magnetization is pinned substantially in one direction, a magnetically free layer having a magnetic material film whose direction of magnetization changes in response to an external magnetic field, and a nonmagnetic metal intermediate layer located between said pinned layer and said free layer. The element also includes a pair of electrodes electrically connected to the magnetoresistance effect film to supply a sense current perpendicularly to a film plane of the magnetoresistance effect film. At least one of the pinned layer and the free layer may include a thin-film insertion layer. The nonmagnetic metal intermediate layer includes a resistance adjusting layer including at least one of oxides, nitrides and fluorides, and the thin-film insertion layer includes at least one element selected from the group consisting of iron (Fe), cobalt (Co) and nickel (Ni).
