摘要: A sensor device having a magnetostrictive force is provided. To detect force, the contains TMR element magnetic detection layer of material magnetostriction coefficient λ≧|5·10−6|, magnetically harder reference layer, and tunnel barrier disposed between these layers. Established in starting magnetization that relative to which directed direction forms an angle other than 0° thus rotated out its position under effect force.
