Abstract:
1. A magnetoresistance effect element comprising: a first magnetization fixed layer whose magnetization direction is fixed; a first magnetization free layer whose magnetization direction is variable; a first nonmagnetic layer sandwiched between said first magnetization fixed layer and said first magnetization free layer; a second magnetization fixed layer whose magnetization direction is fixed; a second magnetization free layer whose magnetization direction is variable; and, a second nonmagnetic layer sandwiched between said second magnetization fixed layer and said second magnetization free layer, wherein said first magnetization fixed layer and said first magnetization free layer have perpendicular magnetic anisotropy, said second magnetization fixed layer and said second magnetization free layer have in-plane magnetic anisotropy, said first magnetization free layer and said second magnetization free layer are magnetically coupled to each other, and center of said second magnetization free layer is displaced from center of said first magnetization free layer in a first plane parallel to each layer.
