Abstract
A nanoscale pillar consisting of a CoCuCo layered structure was fabricated by means of electron-beam lithography to study perpendicular transport properties as a function of both dc electric currents and applied magnetic fields. The nanopillar exhibits sharp transitions in magnetoresistance associated with magnetization reversal between antiparallel and parallel configurations of the two Co layers. Remarked is that the application of a large initializing field of 1 kOe and a current of 16 mA prior to the measurement results in an intermediate state. This intermediate state seems nucleated due to the spin wave instability.
