Nuclear Magnetic Resonance (NMR) study of the nanocrystalline alloy Fe(sub 73.5) Cu(sub 1) Nb(sub 3) Si(sub 13.5) B(sub 9)

摘要

Nanocrystalline Fe(sub 73.5) Cu(sub 1) Nb(sub 3) Si(sub 13.5) B(sub 9) alloys were studied with spin echo NMR at 4.2 K, from 15 to 100 MHz. Several lines are observed, with signals from domains and domain walls. Signals at 50-90 MHz appear to arise from (sup 93) Nb nuclei in the amorphous matrix and in the interface of the crystallites.
