Experimental Evidence for two Kinds of Defects in Amorphous Fe80B20

Abstract

The scattering of cold neutrons (λ = 1 nm) with amorphous Fe80 11B20 yields a strong contribution at small q = (0.07(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
