Abstract:
1. A magnetoresistive effect element comprising: a first magnetic layer which comprises at least one magnetic film and in which a magnetization direction is fixed; a magnetization free layer in which a magnetization direction is changeable; a tunnel barrier layer provided between the first magnetic layer and the magnetization free layer; a non-magnetic metal layer provided on an opposite surface of the magnetization free layer from the tunnel barrier layer, and including a first region and a second region other than the first region in an opposite surface from the magnetization free layer, a surface of the first region being nearer to the magnetization free layer than a surface of the second region; a dielectric layer provided on the first region of the non-magnetic metal layer; and a second magnetic layer which comprises at least one magnetic film and in which a magnetization direction is fixed, the second magnetic layer being provided so as to cover a second region of the non-magnetic metal layer and the dielectric layer.
