The amorphous Fe-Zr-B films prepared by DC magnetron sputtering have been studied using X-ray dif-fraction

XPS and Msbauer spectroscopy

and compared with amorphous ultrafine Fe-Zr-B powder prepared by chemical reduction. The XPS shows that surface of the film is oxidized partly

the interactions among Fe

Zr

B are strong in deeper part. The result of Msbauer spectroscopy shows that Zr and B atoms around Fe atoms cause the re-duction of hyperfine field at Fe nucleus and make the distribution of magnetic hyperfine field with two peaks. This implies that the amorphous Fe-Zr-B film consists of two amorphous microstructures.
