We successfully reproduced the recent experimental results obtained by Chen et al. [Phys. Rev. B {\\bf 74}, 144408 (2006)] and found that the critical current remains finite even in the zero-thickness limit of the free layer. We showed that the remaining value of the critical current is determined mainly by spin pumping.", "revisions": [ { "version": "v2", "updated": "2008-12-31T20:24:32.000Z" } ], "analyses": { "keywords": [ "spin transfer torque-driven magnetization dynamics", "magnetic multilayers", "finite penetration depth", "transverse spin current", "critical current remains finite" ], "tags": [ "journal article" ], "publication": { "publisher": "APS", "journal": "Physical Review B", "year": 2008, "month": "Dec", "volume": 78, "number": 22, "pages": 224421 }, "note": { "typesetting": "TeX", "pages": 6, "language": "en", "license": "arXiv", "status": "editable", "adsabs": "2008PhRvB..78v4421T" } } }
