The. magnetic properties of Fe-C thin film prepared by the ion-beam sputtering method (IBS) using a composite target were investigated. A single-phase Fe_3C thin film was obtained from as-deposited amorphous Fe-C thin films after heated up to 400℃ From magnetization measurement and X-ray diffraction, it was confirmed that the Fe_3C film is single-phase without any impurity phase. Hyperfine parameters were estimated from the results of conversion electron Mossbauer spectroscopy (CEMS) measurement. The central values of the hyperfine field (B_<hr> = 205 kOe), isomer shift (IS = 0.20 mm/s), and quadrupole shift (QS = 0.03 mm/s) for the film are consistent with those for bulk Fe_3C.
