Abstract

Pulsed laser deposition in a uniform high-intensity electrostatic field was used to grow multilayered ⁵⁶Fe/MoS_x/⁵⁷Fe films. The ions of laser-generated plume were significantly accelerated by counter flat fine-cell grid electrode, which was positively charged regarding the substrate. The difference of potentials was 50 kV. This method was recognized to be promising for the efficient intermixing processes in the MoS_x/⁵⁷Fe interface thus initiating the new chemical bond formation in the interfacial layers. By penetrating through the interface the ions gave rise to growth of amorphous layer consisting of rather evenly distributed Fe, S and Mo atoms. The characteristic property of the ion-induced chemical reaction was that the sulfur atoms have efficiently made bonds with iron (FeS₂ type) while the molybdenum atoms transformed into the metallic state and were localized in the environment of Fe atoms. The influence of thermo-chemical properties of Fe-Mo-S system on the characteristic features of the ion-induced processes was also studied.
