Abstract:
1. A magnetoresistive effect element comprising: a nonmagnetic layer having a first surface and a second surface which face each other; a reference layer provided on the first surface and having a fixed magnetization direction; a magnetization variable layer provided on the second surface, having variable magnetization direction, and having a planer shape including a rectangular part, a first projected part, and a second projected part, the rectangular part having a first longer side and a second longer side which face each other and a first shorter side and a second shorter side which face each other, the first projected part projecting from the first longer side at a position shifted from the center toward the first shorter side, the second projected part projecting from the second longer side at a position shifted from the center toward the second shorter side; a first corner made by the first longer side and the first shorter side; a second corner made by the second longer side and the second shorter side; a third corner made by the first longer side and the second shorter side, the third corner being smaller than the first and second corners; and a fourth corner made by the second longer side and the first shorter side, the fourth corner being smaller than the first and second corners.
