Abstract
The short range order of a series of Co100-xPx (17<x<26) amorphous alloys prepared by electrodeposition is studied by EXAFS. The structural parameters as coordination numbers and interatomic distances have been found to vary significantly with P concentration. This behaviour contrasts with that of Fe-P alloys where the environment of the Fe atoms does not change appreciably with composition. The structural differences between both systems are related with clear differences in the magnetic properties, most of all in the dependence on concentration of the Curie temperature.
