Fe thin films with underlayers of various materials were continuously prepared by the evaporation method with an electron beam heating equipment on glass substrates at room temperature. The film thickness dependence of the saturation magnetization I_s and of the coercive force H_c of double-layered Fe/(Ag, Cu, Bi, or Si) films was measured. The largest value of saturation magnetization I_s among the double-layered films was 20 kG, for an underlayer material of Ag with a thickness of 50.0 nm, and was larger than that of Fe thin films deposited directly on glass substrates. The compositions and the surface morphologies of an Fe/Ag double-layered film were also investigated by measuring the AES spectra and the AFM images, respectively. These results indicate that the surface morphology of Fe thin film with underlayer is closely related to the magnetic properties.
