INVESTIGATION OF INTERATOMIC INTERACTION IN MULTILAYER NANOSTRUCTURES (Co45Fe45Zr10/a-Si)40) AND (Co45Fe45Zr10/SiO2)32 BY METHODS OF IR SPECTROSCOPY AND SMALL ANGLE DIFFRACTION

Abstract

The aim of this work is to confi rm the chemical bonds between the components of multilayer nanostructure (MLNS) by IR spectroscopy, the identifi cation of the IR spectra in the MLNS (Co45Fe45Zr10/a-Si)40) and (Co45Fe45Zr10/SiO2)32 with the same metal layers and various interlayersamorphous silicon or silicon dioxide and estimation of their thickness by the method of small-angle X-ray diffraction. The presence of interatomic Co-Fe and Fe-Zr bonds in metallic granules and the bonds with oxygen of metal layers components Fe-O and Co-O and nonmetallic Si-O-Si and Si-O interlayers was confi rmed by IR spectroscopy. Small-angle x-ray diffraction produces refl ections of three types (from bilayers, from metallic layers and from interlayers) only in samples with the thickest interlayers. Samples with the thinnest interlayers do not give comparable refl ections from metal layers and interlayers due to their mixing with the formation of oxide and silicide phases of d-metals.
