Abstract
A magnetic domain wall movement element includes a magnetoresistance effect part, a first electrode, a second electrode, a third electrode, a first magnetization fixed layer, and a second magnetization fixed layer. The magnetoresistance effect part includes a reference layer, a magnetic domain wall movement layer, and a non-magnetic layer. The magnetic domain wall movement layer has a first region and second region in which a magnetization direction is fixed, and a third region in which a magnetization direction is variable. The reference layer overlaps at least part of the first region and the second region in a plan view in a first direction, and at least part of the first region and the second region is shorter than the third region in a third direction orthogonal to the first direction and the second direction.
