Abstract
A magneto-resistance effect element can obtain a high output and makes it possible to stabilize magnetization in a magnetization free layer therein even if a sense current is caused to flow. The magneto-resistance effect element is provided with a magnetization free layer whose magnetization direction is variable, a magnetization pinned layer whose magnetization direction is pinned, and an intermediate layer provided between the magnetization free layer and the magnetization pinned layer, where when no external magnetic field is present and no current flows, the magnetization direction in the magnetization free layer is anti-parallel to the magnetization direction pinned in the magnetization pinned layer, an easy axis of magnetization in the magnetization free layer is parallel to the magnetization direction pinned in the magnetization pinned layer, and a sense current flows from the magnetization free layer to the magnetization pinned layer.
