Abstract
We have studied the resistivity and the magnetoresistance of Ag1-x Rx and Ag0.5 Lu0.5-x Rx amorphous alloys prepared by sputtering (R = rare-earth). Measurements have been performed in pulsed field up to 300 kG. We observe that magnetic ordering can yield positive or negative resistivity changes in these systems. We interpret the experimental results in terms of coherent exchange scattering and two-current conduction.
