Claim 0:
1. A magnetoresistance effect element, comprising:
a first ferromagnetic layer;
a second ferromagnetic layer;
a nonmagnetic layer that is disposed between the first ferromagnetic layer and the second ferromagnetic layer; and
an insertion layer that is disposed at least one of a position between the first ferromagnetic layer and the nonmagnetic layer and a position between the second ferromagnetic layer and the nonmagnetic layer,
wherein the nonmagnetic layer is composed of an oxide containing Mg and Ga,
wherein the insertion layer is a ferromagnetic component containing Ga, and
wherein a Ga concentration of the insertion layer is lower than a Ga concentration of the nonmagnetic layer.
