Abstract
A magneto-resistance effect element includes: a first ferromagnetic layer serving as a magnetization fixed layer; a magnetization free layer including a second ferromagnetic layer provided on one side of the first ferromagnetic layer, a third ferromagnetic layer which is formed on an opposite side of the second ferromagnetic layer from the first ferromagnetic layer and has a film face having an area larger than that of the second ferromagnetic layer and whose magnetization direction is changeable by an external magnetic field, and an intermediate layer provided between the second ferromagnetic layer and the third ferromagnetic layer; and a tunnel baffler layer provided between the first ferromagnetic layer and the second ferromagnetic layer. The second ferromagnetic layer and the third ferromagnetic layer are magnetically coupled via the intermediate layer, and an aspect ratio of a plane shape of the third ferromagnetic layer is within a range from 1 to 2.
