Abstract
The scattering of cold neutrons (λ = 1 nm) with amorphous Fe80 11B20 yields a strong contribution at small q=4π (0.7 (nm)-1 ≤ q ≤ 2.4 (nm)-1 arising from two kinds of defects of different size : i) local defects with an extent of about 1.5 nm ii) Extended defects with an extent of about 40 to 60 nm, which are interpreted as quasi-dislocations in the amorphous material.
