| Popis: | Amorphous alloys of Fe85 –xCrxB15 (x = 0–20) obtained by ultrafast melt quenching are investigated by the pulsed 11В nuclear magnetic resonance (NMR) method at a temperature of 4.2 K. The amorphous alloys consist of microdomains (nanoclusters) with short-range orders of the tetragonal (Fe,Cr)3B and α-(Fe,Cr)(B) phases, containing chromium atoms in the nearest neighbor environment of the iron atoms. The mean magnetic moments of the magnetic atoms in the nearest sphere of the boron atoms and their dependence on the composition in the nanoclusters are estimated. |
