Abstract
A magnetic storage device includes a laminated structure and a third magnetic body. The laminated structure includes a first magnetic body, a nonmagnetic body, and a second magnetic body which are laminated. The third magnetic body is provided at any of a first magnetic body side and a second magnetic body side. Resistance of the laminated structure is changed based on a difference between magnetization directions of the first magnetic body and the second magnetic body. A projection of the third magnetic body onto the first magnetic body at least partly overlaps the first magnetic body. The first magnetic body and the third magnetic body are magnetically coupled. A planar shape of the first magnetic body is a shape that is long in a first direction. A length of the third magnetic body is shorter than a length of the first magnetic body in the first direction. An aspect ratio of a length of a long-axis direction of the planar shape of the first magnetic body divided by a length of a short-axis direction is greater than an aspect ratio of a length of a long-axis direction of a planar shape of the third magnetic body divided by a length of a short-axis direction.
