    摘要: A spin FET includes a first ferromagnetic film disposed on a first source/drain area, a direction of magnetization thereof being fixed in an upward direction or a downward direction perpendicular to a film surface, a second ferromagnetic film disposed on a second source/drain area, a direction of magnetization thereof being changed in the upward direction or the downward direction, an anti-ferromagnetic ferroelectric film disposed on the second ferromagnetic film, and a tunnel barrier film disposed at least between the first source/drain area and the first ferromagnetic film or between the second source/drain and the second ferromagnetic film. Resistance of the anti-ferromagnetic ferroelectric film is larger than ON resistance when the first and second source/drain areas conduct electricity through the channel area.
