摘要：

We introduce here a novel technique specifically designed to measure the thermoelectrical properties of nanoscale ferromagnetic wires, prepared by electrodeposition in nanoporous membranes. The conditions of measurements have been determined through experiments performed on uniform Co and Cu wires made in different kinds of membranes at different temperatures, from 300 K down to 70 K. We then investigated the magnetic field dependence of Co-Cu multilayer nanowires in the current-perpendicular-to-plane geometry: the relation between the giant magnetoresistance and the magnetothermopower demonstrated the efficiency of this experimental technique.
