Abstract

For Ta/Fe50Mn50/Ta, Ta/Dy/Ta, and Ta/Co90Fe10/Ta nanostructures prepared by magnetron sputtering, a positive longitudinal magnetoresistance due to the spin Hall effect was found. The difference in the magnitude of magnetoresistance and the shape of magnetoresistive curves obtained for nanostructures with layers of metals with different types of magnetic ordering is interpreted under the assumption of different magnitude of purely spin current injected into the magnetics layer.
