Abstract

The structural peculiarities and the influence of electrolytic polishing, plastic deformation by rolling, and composition's modification on surface's atomic structure of amorphous ribbons have been studied. The experimental results obtained by means of spectroreflectopolarimetric and Fourier-spectroscopic techniques for some 3D-metal based disordered alloys are presented and discussed. The structural anisotropy of both sides of as-casted ribbons for amorphous alloys was found. The anisotropy was characterized by the difference of principal angles of incidence determined under two orthogonal orientations of ribbon: parallel and perpendicular to the p- direction respectively. It has been determined that electrolitical polishing of the ribbon's surface has not changed essentially the behavior of optical conductivity spectra. We determine that plastic deformation by rolling causes the increasing of intensity of free electrons scattering on structural defects due to the enhancement of their concentration.
