Abstract

In order to monitor the peculiar temperature dependence of the magnetization of the compounds YCo4B and CeCo4B from an atomistic point of view, samples doped with 1%57Fe were studied by Mössbauer spectroscopy. From the two Co-sites present in this structure (2c, 6i), only the latter were found to be equipped by Fe. In the case of the Y-compound, the change of direction of the easy axis of magnetization could be confirmed. The broad maximum observed for the magnetization of the Ce-compound is not reflected by the57Fe hyperfine field.
