Particle Morphology and Phase Compositions of CoPt and CoPd Nanostructured Systems in the Regions Rich in Precious Metals

The morphology of nanoparticles, structural -phase properties, and phase transformations that occur during heating in the nanostructured CoPt and CoPd systems rich in precious metals, obtained by co -reduction of aqueous precursor solutions by hydrazine hydrate, were studied by X-ray diffraction and X-ray structural analysis, smallangle X-ray scattering, and high -resolution transmission electron microscopy. The results obtained are of interest for the development of the fundamentals of materials science of bimetallic nanoalloys, and provide a key to understand the processes of the formation of FePt, CoPt and FePd nanoalloys while heating intermetallic compounds with a highly ordered structure L1(0), which possess record -setting magnetic and magneto -optical properties.
