Abstract
The magnetoresistance (MR) of magnetic multilayers. Fe/Cr and Co/Cu, was measured at high pressure. It was found that the effect of pressure on the MR depends on the specimen: the MR of Fe/Cr decreases much more than that of Co/Cu. The large effect of pressure on the MR in Fe/Cr is shown to be due to the suppression of spin-dependent scattering at high pressure. The relation between the effect of pressure on GMR and the interfacial roughness is discussed briefly.
