Abstract

The experimental results obtained by methods of linear and nonlinear optics and their discussion for pure metal (Ag, Au, Cu, Al, Ni, Cr), and Fe- and Ni-based amorphous alloys are performed. It is shown that from both linear spectroreflectopolarimetric and the second- harmonic generation data, the parameters characterizing surface roughness may be evaluated, moreover in the latter the sensitivity to the surface effects is in two orders higher than that for ellipsometry. The greater the roughness, the smaller is the intensity of s-component of the second harmonic generation. The structural anisotropy of both sides of the ribbon for amorphous alloys is found. This results in the difference of the principal angles of incidence, measured for two orthogonal orientations relative to p-plane from each of the ribbon's sides.
