“…Intermetallic phases formed by solid-state reactions in thin-film structures play an important role from a technological point of view because of their applications, ranging from use as heat-and corrosion-resistant coatings for bulk materials [6,7] to use as metallization layers in microelectronic devices [8,9]. In particular, Fe-Al-based alloy films, such as Fe-Al-Si (Sendust alloy) and Fe-Al-Si-Ni (Supersendust alloy), have been widely used as magnetic recording head materials because of their soft magnetic and good mechanical properties [10][11][12].…”

The phase formation during thermal annealing of Fe/Al multilayer thin films prepared by electron-beam evaporation, with an overall atomic concentration ratio of Fe:Al = 1:1, has been studied by Rutherford backscattering spectrometry (RBS), x-ray diffraction spectroscopy (XRD), and conversion-electron Mössbauer spectroscopy (CEMS). At the annealing temperature of 473 K some degree of atomic mixing between Fe and Al layers is revealed only by CEMS. At 573 K a large degree of atomic mixing is indicated also by RBS, leading to the nucleation and growth of the B2 FeAl intermetallic phase, as detected by means of XRD and CEMS. At 673 K all Fe atoms have reacted and the multilayer film is transformed into a defective B2 phase. Annealing at higher temperature increases the structural order of the B2 phase. We suggest that the observed phase formation occurs in three stages: (1) formation of a thin intermixed layer between Fe and Al in the as-deposited sample; (2) Al migration into the initial intermixed layer; (3) B2 phase growth at the interface between the intermixed layer and the Fe layer.

Fe-Al-Si-Ni supersendust films containing 2.7 at. % Ni atoms with a thickness of 1 μm were deposited on crystallized-glass substrates by rf planar magnetron sputtering, and the changes in magnetic properties and structure due to the sputtering conditions and annealing were examined. The films with excellent soft magnetic properties and high magnetic-flux density which are good candidates for new recording-head materials were obtained by annealing as-deposited films at 500 °C. It was found through conversion electron Mössbauer spectroscopy (CEMS) that the disordered structure of α type in as-sputtered films transformed into the ordered structure consisting of a mixture of B2 and DO3 types at the temperature of 500 °C. The CEMS studies also revealed that Ni atoms are located at the corner in the bcc structure.
