Abstract
By combining electromagnetic levitation with the EXAFS method it is possible to investigate the short-range order of metallic melts in a wide temperature range. Due to the containerless environment it is even possible to obtain insight into the metastable state of a deeply undercooled melt not amenable by other methods. This allows us to study the solid and the liquid state in the same temperature range. Here we report on the first quantitative EXAFS measurements on a liquid ${\mathrm{Co}}_{80}{\mathrm{Pd}}_{20}$ alloy undercooled by more than $300\ifmmode^\circ\else\textdegree\fi{}\mathrm{C},$ and on solid ${\mathrm{Co}}_{80}{\mathrm{Pd}}_{20}.$ From the spectra, we have obtained the temperature dependence of the neighbor distances as well as of the Debye-Waller factors.
