Abstract
We show that by ion-beam sputtering of a 304 L stainless steel target under ultra high
vacuum, it is possible to elaborate thin films exhibiting both a bcc single phase and a strongly
ferromagnetic structure at 293 K. The hyperfine field measured at the 57Fe nucleus using the
Mössbauer effect is studied in details as a function of sample thickness. The field value is
close to that of bulk α-iron while the direction of the magnetization lies in the film plane
when the thickness of the sample is - 0.4 µm. Experimental values are compared with data
available in the literature. The possible role of chromium atoms is also discussed.
