Hyperfine fields and local environment in iro-boron metallic glasses

The concentration dependence of the average hyperfine field and the hyperfine field distribution in Fe100-xBx metallic glasses (0hard spheres' model structures. It is assumed that the hyperfine field at iron sites without boron neighbours is sensitive to local compression or dilation in analogy to crystalline close-packed iron. In this way even the strong decrease of the average hyperfine field at low boron content can be explained.
