Abstract
Magnetoresistance (MR) has been investigated for Au-rich Co-Au and Fe-Au bulk aged granular alloys. A negative isotropic MR is observed at room temperature. In particular, the room-temperature value of MR of 5.5% in the Co15Au85 bulk granular alloy aged at 250 degrees C for 1 h is larger than that reported for Co/Au multilayers.Keywords
