中文摘要	In this letter, we present a study on the magnetic coupling and magnetoresistance (MR) properties in Fe/Si1-xAgx multilayers (MLs) with a granular Si1-xAgx spacer layer. We found that with increasing silver content (x) in a silicon matrix, the magnetic state of MLs varies from a nonmagnetic-coupling state to a weak-antiferromagnetic state around the percolation point of the similar to24-Angstrom-thick granular spacer Si1-xAgx. The MR measurements also reveal an abrupt increase of MR near the same percolation point. These variations are ascribed to the formation of the percolation path in the granular spacer.
