Combined EXAFS and X-Ray Scattering Investigation of Amorphous Zr-Based Alloys

EXAFS spectra for all K absorption edges and X-ray scattering data have been obtained on an amorphous Fe-Zr sample prepared by mechanical alloying and a rapidly quenched Co-Zr one. Partial pair distribution functions have been determined as a solution of an inverse ill-posed problem for the system of integral equations describing combined experimental data. For Fe-Zr and Co-Zr amorphous alloys we find a high degree of chemical order and also non-Gaussian nearest neighbour distribution
