|Title:||Exafs Characterization Of Cobalt Nanoparticles Embedded In A Copper Matrix|
Martins Alves M.C.
Da Suva F.C.S.
|Abstract:||In this work samples with different microstructures, departing from as-quenched Cu100-xCox (x = 3, 10 e 25) melt-spun ribbons, were studied using the X ray absorption spectroscopy (XAS) technique. The spectra (XANES, EXAFS) of these samples, as well as of pure fee Cu and hep Co used as reference, were measured in the XAS beam-line of LNLS. As a function of heat treatment, the spectra in the Co K edge region shift, in terms of average Co-metal distances, from fee Cu towards pure hep Co. A detailed analysis of this evolution could, in principle, give indications of the Co clusters size. ©1999 Trans Tech Publications.|
