Study on the Sensing Function in Amorphous Magnetic Thin Films

In this paper, we prove through the experiments the possibility that Co-amorphous magnetic films can be used as high sensibility materials. We fabricate amorphous film of Fe$\sub$4.7/Co$\sub$74.3/Si$_2$B$\sub$19/ by using sputtering method at high frequency. Then, we not only measure the magnetic Properties of the annealed samples, but also observe the magnetic domain by using an Kerr effect optical-microscope. As the result, we find that the samples have high sensibility
