| Abstract: |
We have imaged the magnetic domain structure of several heterogeneous CoxAg1-x alloys by using scanning electron microscopy with polarization analysis. These images show that extended domain structures exist in both the as-deposited samples and in samples annealed at moderate temperatures. This suggests that a significant fraction of the cobalt in these materials does not contribute to the giant magnetoresistance. Only those samples annealed at 600° C and containing less than 40% cobalt by volume show no domain structure. |
