M. Miglierini et al., JOULE HEATING OF FE-B METALLIC GLASSES, Nuclear instruments & methods in physics research. Section B, Beam interactions with materials and atoms, 76(1-4), 1993, pp. 113-114
Amorphous Fe80B20 and Fe83B17 ribbons were heated in air and in vacuum
, respectively, by a dc electric current passing through the specimen.
During the Joule heating, Fe-57 transmission Mossbauer spectra were r
ecorded. Ribbons of the same geometrical dimensions, cut from a natura
l iron foil, were treated in the same way as a reference. The influenc
e of the current-induced magnetic field in addition to the Joule heati
ng is supposed to cause fluctuations in a short-range order observed.
Changes in the hyperfine magnetic fields are compared with those obtai
ned by a conventional heating in a vacuum furnace.
