Abstract:
CThe comparison of the resonance magnetic absorption spectra with the data on structure and magnetic properties of Fe$_{67}$Cr$_{18}$B$_{15}$ amorphous samples has shown that a randomly inhomogeneous medium of amorphous alloy is multiphase. Two types of samples with the same chemical composition, but with a different clusterized structure, and the use of (Ar$^+$) ion irradiation in the experiment made it possible to separate four basic phases with different magnetic properties. The basic phase $\alpha$-(Fe,Cr) contains large clusters of $D<$ 400 $\mathring{\mathrm{A}}$ in size with a tendency to phase separation of iron ($\alpha$-Fe) and chromium ($\alpha$-Cr), which under irradiation, enhances the competing FM and AFM magnetic interactions and increases the intensity of the resonance magnetic absorption lines associated with $\alpha$-Fe and $\alpha$-Cr. The phase Fe$_3$B ($D<$ 100 $\mathring{\mathrm{A}}$) is detected by independent line in the resonance absorption spectra only when its groupings are isolated from the $\alpha$-(Fe,Cr) metal phase clusters. The fourth phase contains precluster groupings and disappears when the sample is irradiated.
