Abstract
The structural, magnetic and magnetoresistance properties of CoFe/Ag multilayers prepared by magnetron sputter were studied. The uniformity of multilayer was optimized when the multilayer was prepared under 2 mTorr Ar/10%H₂atmosphere and 100 Ｗ input power. Although the structural evolution of discontinuous multilayer was slow, the increase of MR ratio and the structural stability was high when the multilayer was uniform. The MR ratio of CoFe 12 Å/Ag 70 Å multilayer, which was annealed for 20 minutes at 350℃ was 3.8% and the saturation field was 90 Oe.
