Abstract:
1. A magnetoresistance effect element, comprising: 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 nonmagnetic metal intermediate multilayers located between said magnetically pinned layer and said magnetically free layer; and a pair of electrodes electrically connected to said magnetoresistance effect film to supply a sense current perpendicularly to a film plane of said magnetoresistance effect film, at least one of said magnetically pinned layer and said magnetically free layer including a thin-film insertion layer, said nonmagnetic metal intermediate multilayers having a resistance adjusting layer that is composed of Cu—Cr oxide or Cu—Al oxide, and said thin-film insertion layer composed of iron (Fe) and cobalt (Co).
