FEATURES OF A STRUCTURAL ANALYSIS OF MULTICOMPONENT NANOMATERIALS AND MATERIALS WITH A LOW PHASES CONCENTRATION BY XANES SPECTROSCOPY
This article describes the features of X-ray absorption by materials, establishes the principles of XANES spectroscopy and its field of application, and advantages and disadvantages. Also considered the realization of this technique by the method of near edge X-ray absorption fine structure determination and equipment. Electronic structure and phase composition determination in multilayer nanocomposites (Co<sub>4</sub>5Fen<sub>5</sub>Zr<sub>10</sub>/a-Si)<sub>4</sub>o and (Co<sub>45</sub>Fe45Zri<sub>0</sub>/SiO<sub>2</sub>)3<sub>2</sub> is shown as an example of the use of XANES in amorphous nanostructures study.
