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 15300 K. Application of the two-current model to thermopower yields (S-up arrow - S-down arrow)/(S-up arrow + S-down arrow) the relative difference between the thermopower of each spin channel
