摘要：
A two-channel model of electronic conduction is shown to provide a satisfactory description of the magnetoresistances of Ag/Co and AgSn/Co multilayers with the - current flowing perpendicular to the layer planes. A combination of data for as-prepared samples at magnetic field H=0 (for which the magnetization M almost-equal-to 0), and for the same samples in the ferromagnetically ordered state, is used to extract ''best'' spin-orientation-dependent parameters of alpha(Co)=2.9(+0.5, -0.3) and alpha(Co/Ag)=12(+5, -2) from Ag/Co data and alpha(Co)=2.4(+1, -0.7) and alpha(Co/Agsn)=11(+7, -4) from AgSn/Co data.
