The domain wall behavior was investigated both experimentally using focused magneto-optic Kerr effect measurements of lithographically patterned nanowires and with micromagnetic simulations. The pinning behavior observed is utilized in a concept for multibit memory cells applicable as the free layer in magnetic random access memory where the domain structure is defined by the location of domain walls that either pin or passby pinning structures depending upon the domain wall configuration selected. date: 2008-01-14 date_type: published official_url: https://doi.org/10.1063/1.2832771 oa_status: green full_text_type: pub language: eng primo: open primo_central: open_green article_type_text: Article verified: verified_manual elements_id: 1297865 doi: 10.1063/1.2832771 lyricists_name: Bogart, Lara lyricists_id: LKBOG81 actors_name: Bogart, Lara actors_id: LKBOG81 actors_role: owner full_text_status: public publication: Applied Physics Letters volume: 92 number: 2 article_number: 022510 issn: 1077-3118 citation: Atkinson, D; Eastwood, DS; Bogart, LK; (2008) Controlling domain wall pinning in planar nanowires by selecting domain wall type and its application in a memory concept.
