We have found that the ratio of the MR of the resonant peak current is reduced more than that of the single junction, whereas that of the valley current is enhanced depending on the change of the discrete energy-level under the change of magnetic field. We also found that the peak current-valley current (PV) ratio decreases when the junction conductance increases.", "revisions": [ { "version": "v1", "updated": "1998-06-26T07:19:45.000Z" } ], "analyses": { "keywords": [ "resonant tunneling", "uantum dot", "magnetoresistance", "junction conductance increases", "resonant peak current" ], "tags": [ "journal article" ], "publication": { "publisher": "APS", "journal": "Phys.
