By considering the transport paths for a single electron incident at the local F/S interface - in terms of probabilities of crossed or local Andreev reflection, elastic cotunneling or quasiparticle transport - we show that this leads to nonlocal charge imbalance. We compare this model with experimental data from an aluminum-permalloy (Al/Py) lateral spin valve geometry device and demonstrate the effectiveness of this simple approach in replicating experimental behavior.", "revisions": [ { "version": "v2", "updated": "2012-07-16T15:18:43.000Z" } ], "analyses": { "subjects": [ "74.45.+c", "74.40.Gh", "74.78.Na", "75.75.-c" ], "keywords": [ "crossed andreev reflection", "charge imbalance", "numerical model", "spin valve structure consisting", "lateral spin valve geometry device" ], "tags": [ "journal article" ], "publication": { "doi": "10.1103/PhysRevB.86.054525", "journal": "Physical Review B", "year": 2012, "month": "Aug", "volume": 86, "number": 5, "pages": "054525" }, "note": { "typesetting": "TeX", "pages": 9, "language": "en", "license": "arXiv", "status": "editable", "adsabs": "2012PhRvB..86e4525W" } } }
