<p>A magnetic storage device is provided with a laminated structure wherein a first magnetic body, a nonmagnetic body and a second magnetic body are laminated; and a third magnetic body which is arranged either on the side of the first magnetic body or the side of the second magnetic body. Resistance of the laminated structure varies by a difference between the magnetization direction of the first magnetic body and that of the second magnetic body. Projection of the third magnetic body to the first magnetic body at least partially overlaps with the first magnetic body. The first magnetic body and the third magnetic body are magnetically coupled. The planar shape of the first magnetic body is long in a first direction. The length of the third magnetic body is shorter than that of the first magnetic body in the first direction. An aspect ratio, which is obtained by dividing the length of the planar shape of the first magnetic body in a long axis direction by the length in a short axis direction, is larger than the aspect ratio of the third magnetic body.</p> |
