Peculiarities of Disorder-Induced Ferromagnetism Phenomena in Fe₆₀A₄₀ films on a local scale

Evolution of the magnetic hyperfine field profiles in an ion-irradiated Fe60Al40 film measured by nuclear resonant reflectivity

“…The fitting results demonstrate that the relative weight of the magnetically split resonant contributions increases with increasing irradiation fluence. These findings are in agreement with the results obtained from XMCD measurements at the Fe K edge (La Torre et al, 2018) and from soft X-ray studies (Smekhova et al, 2021).…”

“…By means of X-ray magnetic circular dichroism (XMCD) and analysis of extended X-ray absorption fine structure (EXAFS) measurements, performed on beamline ID12 at the European Synchrotron (ESRF), it was shown that an increase in the irradiation fluence provided a progressive rise in the Fe magnetic moment, revealing the occurrence of a change in the chemical disorder in the Fe 60 Al 40 alloy (La Torre et al, 2018). Recent XMCD results obtained with soft X-rays at the Helmholtz-Zentrum Berlin (HZB) have confirmed these findings (Smekhova et al, 2021).…”

“…An Fe 60 Al 40 thin film of $40 nm thickness was prepared by magnetron sputtering on an SiO 2 (150 nm)/Si(001) substrate with further annealing in a vacuum at 773 K for 1 h to obtain the B2 ordered structure. B2 ordering is indicated by the occurrence of the 100 superstructure reflections (Bali et al, 2014;Ehrler et al, 2020;Smekhova et al, 2021). For the present experiment the sample had a size of $ 5 mm  10 mm.…”
