The method relies on the measurement of the dipolar repulsion of parallel domain walls that define a linear domain. The film magnetization is linked to the field compressibility of the domain. The method also yields the minimal distance between two walls before their merging, which sets a practical limit to the storage density in spintronic devices using domain walls as storage entities.", "revisions": [ { "version": "v1", "updated": "2013-07-24T16:19:24.000Z" } ], "analyses": { "keywords": [ "perpendicular anisotropy", "domain compressibility", "cofeb films", "measurement", "soft ultrathin films" ], "tags": [ "journal article" ], "publication": { "doi": "10.1063/1.4869482", "journal": "Applied Physics Letters", "year": 2014, "month": "Mar", "volume": 104, "number": 12, "pages": 122404 }, "note": { "typesetting": "TeX", "pages": 0, "language": "en", "license": "arXiv", "status": "editable", "adsabs": "2014ApPhL.104l2404V" } } }
