After inducing DNP, we measure the temperature dependence of the magnetoresistance by a small current over a short period of time. We find that the FQHS makes a phase transition to an insulating state. By measuring the Hall resistance in the insulating state, we find that the RES exhibits a quantized Hall resistance. We discuss the RES in association with the Anderson localization.", "revisions": [ { "version": "v1", "updated": "2013-10-02T07:55:58.000Z" } ], "analyses": { "keywords": [ "current-induced nuclear spin polarization", "insulating state", "phase transition", "fractional quantum hall state", "hall resistance" ], "note": { "typesetting": "TeX", "pages": 5, "language": "en", "license": "arXiv", "status": "editable", "adsabs": "2013arXiv1310.0614T" } } }
