Spin-dependent thermopower in Co/Cu multilayer nanowires

The magnetic field dependence of the thermoelectrical power of a series of Co/Cu multilayered nanowires grown by electrodeposition in a polymer matrix is almost that predicted by the Mott formula in the temperature range of 15–300 K. Application of the two-current model to thermopower yields ( S ↑−...

Zusammenfassung:	The magnetic field dependence of the thermoelectrical power of a series of Co/Cu multilayered nanowires grown by electrodeposition in a polymer matrix is almost that predicted by the Mott formula in the temperature range of 15–300 K. Application of the two-current model to thermopower yields ( S ↑− S ↓)/( S ↑+ S ↓), the relative difference between the thermopower of each spin channel.
