Abstract
A domain wall motion element has a magnetic recording layerthat is formed of a ferromagnetic film and has a domain wall DW. The magnetic recording layerhas: a pair of end regions-and-whose magnetization directions are fixed; and a center regionsandwiched between the pair of end regions-and-, in which the domain wall. DW moves. A first trapping site TSby which the domain wall DW is trapped is formed at a boundary between the end region--and the center region. Furthermore, at least one second trapping site TSby which the domain wall DW is trapped is formed within the center region
