Abstract

Magnetoresistive (MR) and magnetic properties of Co-Ag alloy films evaporated in ultrahigh vacuum were studied. The measured MR ratios were 24.7% at room temperature (RT) for Co4oAg6o (at%) alloy film and 48.6% at 77 K for Co32 Ag68 alloy film. In addition, the MR profile shows an anistropy between two applied field directions, transverse and normal to the current in plane. This anisotropy is caused by the pancake-shaped Co clusters.
