Swift Heavy Ion Irradiation-Induced Amorphous Iron and Fe-Si Oxide Phases in Metallic *5*7Fe Layer Vacuum Deposited on Surface of SiO&sub(2)/Si / E.Kuzmann, V.A.Skuratov, L.Krupa, [a.o.] // Journal of Materials Research [Electronic resource]. – 2023. – Vol. 38, No. 4. – P. 1061-1073. – URL: https://doi.org/10.1557/s43578-022-00767-z. – Bibliogr.:83.

57 Fe conversion electron Mössbauer (CEM) spectroscopy, SEM and magnetization measurements were used to study the effect of swift heavy ion irradiation on metallic 57 Fe (10 nm) thin layer vacuum deposited onto SiO 2 /Si. About 85% of the total iron content of the surface layer detected by CEM was present as metallic, crystalline alpha iron before the irradiation, while upon irradiation with 160 MeV Xe ions, with a fluence of 5 × 10 13 ion cm −2 , ~ 21% was converted to amorphous iron and ~ 47% to silicon- containing iron oxide phases. The presence of pure iron in the amorphous state was evidenced by CEM in agreement with magnetization measurements. Temperature dependence of CEM measurements and the FC/ZFC curves of the irradiated deposit indicated superparamagnetic nature of the iron-silicon-oxide phases. The results are discussed in terms of the thermal spike model for the formation of the amorphous iron phase that can be essential for the formation of silicon-iron-oxides.
