Abstract
A magnetic domain wall movement element according to the present embodiment includes a first ferromagnetic layer, a nonmagnetic layer, and a second ferromagnetic layer that are laminated in an order from a side close to a substrate. On a cross-section along a lamination direction and a second direction orthogonal to a first direction in which the first ferromagnetic layer extends in a plan view from the lamination direction, a shortest width of the first ferromagnetic layer in the second direction is shorter than a width of the nonmagnetic layer in the second direction.
