Abstract
The discovery of the giant magnetoresistance (GMR) effect in Fe/Cr multilayers [1] has stimulated a remarkable interest in these and other similar multilayers, due to its potential application in magnetic sensors and recording heads. Recently, it was demonstrated that GMR is also exhibited by nonmultilayer heterogeneous samples containing ferromagnetic granules embedded in a nonmagnetic matrix [2, 3]. Here, no coupling between the magnetic entities (as it is the case of multilayers) is necessary to explain the appearance of the GMR; spin dependent scattering originates from randomly oriented single domain regions.
