Magneto seebeck effect
WebGiant magnetoresistance and magneto-Seebeck effects were measured with amplitudes of up to 17% and −25%, respectively, for the Ni 80 Fe 20 /Cu multilayered nanowire network. Although similar field behaviors for magnetoresistance and magneto-Seebeck effects were observed for all samples, the two effects could have very contrasting amplitudes. WebThermally induced spin-dependent transport across magnetic tunnel junctions is theoretically investigated. We analyze the thermal analog of Slonczewski’s model (as well as its limiting case—Julliere’s model) of tunneli…

WebHere, we demonstrate the observation of one important effect of this class: the magneto-Seebeck effect. It is observed when a magnetic configuration changes the charge-based Seebeck coefficient. In particular, the Seebeck coefficient changes during the transition from a parallel to an antiparallel magnetic configuration in a tunnel junction. In conclusion, we have presented an experimental study of the spin-dependent Seebeck effect in Heusler compound based MTJs.
