US 2017/0256705 A1 · MAGNETORESISTIVE ELEMENT AND METHOD OF MANUFACTURING THE SAME

Abstract

A magnetoresistive effect element according to one embodiment includes: a first magnetic layer; a nonmagnetic layer; a second magnetic layer; a metal layer; and a third magnetic layer. An area of a bottom of the third magnetic layer is larger than an area of a top of the third magnetic layer. An angle between the top of the third magnetic layer and a side of the third magnetic layer is larger than an angle between a top of the second magnetic layer and a side of the second magnetic layer, or an angle between the bottom of the third magnetic layer and a side of the third magnetic layer is smaller than an angle between the bottom of the second magnetic layer and a side of the second magnetic layer.
