Abstract
We have studied the magnetotransport and magnetic properties of a metallic granular FexAg100−x system, fabricated by using a magnetron cosputtering technique. Giant magnetoresistance was observed in a narrow range between x=10 and 25 vol %. Both the Fe volume fraction and the sample orientation significantly influence the magnetoresistance. This granular system also demonstrates some unique features as compared to multilayer systems.Keywords
