  Nanodot deposition on a side surface of a rectangular sample and digital
image correlation are used to quantify the in-plane strain fields associated
with the propagation of a shear band in a PdNiP bulk metallic glass,induced by
rolling. Within the resolution of the method related to an average inter-dot
distance of 100 nm, deformation is found to be highly localized at the shear
bands, while alternating areas with a size of 100 - 400 nm with opposite local
shear strains are found. This phenomenon substantiates a local stick-slip
nature of shear band propagation during the metallic glass deformation, even
during rolling.
