[en] Bulk metallic glasses (BMG) are amorphous solids which are very well
known for their excellent mechanical properties. In this contribution,
we focus on their magnetic behavior and we discuss the influence of
mechanical deformation on the magnetic microstructure as seen by
magnetic-field-dependent small-angle neutron scattering (SANS). This
technique allows one to investigate the spin distribution in the bulk
of the material and on the nanometer length scale. We present and
compare the results of unpolarized SANS on various BMG samples
(as-cast, aged, deformed) and we analyze the SANS cross section in
real space by computing the correlation function.
