Figure 2: Spin-valve MR and anisotropic MR
(AMR) versus Fe thickness for a series of 5
Fe(tFe)-Cu(61Å)-Co(55Å)-Cu(36Å)
sandwiches grown on silicon substrates at 160 ûC. The
spin-valve MR is the isotropic component of the total MR. The
dashed line is a fit to the AMR data with form AMR = 0.097% +
(0.002%/Å)tFe.
