Abstract
Simultaneous magnetoresistance measurements and observation of magnetic domain structures have been performed on active spin-valve elements by means of in situ experiments in a Lorentz transmission electron microscope. Two different spin-valve structures with NiFe and NiFe/Co sense layers have been studied with two sizes of rectangular elements. The effect of different applied current values has been analyzed and the addition of a Co layer in the sense layer has a large influence on the spin-valve behavior and on the domain structure. Also, two different processes for magnetic domain growth and motion have been observed for low or high applied current densities.
