Abstract:
1. A magnetoresistive element comprising: a base layer; a first magnetic layer provided on the base layer, and including a first magnetic film having an axis of easy magnetization in a direction perpendicular to a film plane, the first magnetic film including Mn a first nonmagnetic layer provided on the first magnetic layer; a second magnetic layer provided on the first nonmagnetic layer, and including a second magnetic film having an axis of easy magnetization in a direction perpendicular to a film plane, the second magnetic film including Mn an interfacial layer provided between the first magnetic layer and the first nonmagnetic layer, and/or between the second magnetic layer and the first nonmagnetic layer, the interfacial layer including a Heusler alloy, the first and second magnetic layers comprising different Mn composition rates from each other, the first magnetic layer having a smaller Mn concentration than the second magnetic layer, a magnetization direction of the first magnetic layer being changeable and a magnetization direction of the second magnetic layer being unchangeable.
