Abstract
Magnetization reversal in multilayers occurs through the nucleation and pro pagation of domain walls (DWs). We find that in antiferromagnetically coupl ed [Fe/Cr](10) multilayers in a wide temperature interval above 1.9 K, the resistivity associated with DW scattering, rho(DW), varies as rho(DW)(T) = rho(DW)(0) - AT(alpha) with the exponent alpha similar or equal to 0.7-1. T his possibly indicates the presence of quantum interference effects in the quasiballistic electron transport through domain walls. (C) 2000 Elsevier S cience B.V. All rights reserved.
