In this system, spin-orbit interaction has substantial influence on the spin states of confined electrons. Pumping single electrons through a Pauli spin-blockade configuration allowed to probe the dynamics of the two coupled spins via their influence on the pumped current. We observed spin-relaxation with a magnetic field dependence different from GaAs dots, which can be explained by spin-orbit interaction. Oscillations were detected for times shorter than the relaxation time, which we attribute to coherent evolution of the spin states.", "revisions": [ { "version": "v1", "updated": "2008-07-23T13:08:23.000Z" } ], "analyses": { "subjects": [ "73.63.Kv", "72.25.-b", "71.70.Ej" ], "keywords": [ "strong spin-orbit interaction", "coupled spins", "two-electron spin states", "pauli spin-blockade configuration", "magnetic field dependence" ], "tags": [ "journal article" ], "publication": { "publisher": "APS", "journal": "Physical Review B", "year": 2009, "month": "Mar", "volume": 79, "number": 12, "pages": 121306 }, "note": { "typesetting": "TeX", "pages": 5, "language": "en", "license": "arXiv", "status": "editable", "adsabs": "2009PhRvB..79l1306P" } } }
