In this paper, the authors have been studying on magnetic and electric properties of ferromagnetic substance/semimetal, Fe/Bi, system multilayered thin films prepared by ion-beam sputtering method. The multilayered thin film was prepared with 99.6%Fe and 99.99%Bi. The experimental results are summarized as follow:From the result of XRD in small degrees region (2θ=2-4 deg.), Fe/Bi system thin films at number of Fe layers, N=3,4 and 5 have been formed structure of multilayers. Coercive force H_c increased with the rising at number of Fe layers. And maximum value was 4.522kA/m at number of Fe layers, N= 6. Then, coercive force decreased and its value was constant at more than 15 layers. Resistivity, ρ, of Fe/Bi system multilayered thin films was changed from conductivity to semiconductivity at temperatures range of T=380˜400K. Magneto-resistance (MR) ratio was decreased with increasing applied field H when current is parallel to an applied magnetic field (I//H ). MR ratio was maximum value of 0.154% at number of Fe layers, N=4, at room temperature.
