Abstract

The magnetic properties of Fe₃Pt compound depend on the degree of disorder present in the system. We have compared a cold-rolled, disordered sample with a heat treated, ordered sample using circularly polarized synchrotron radiation at the Fe K (7112 eV) and at the Pt L₃ (11 564 eV) absorption edge, as well as by Mossbauer spectroscopy, and x-ray diffraction. Fe-K edge dichroism is compared to the measurements of Faraday rotation using linearly polarized radiation. We found that the magnitude of magnetic dichroism at the Pt L₃ edge is reduced when the disordered Fe₃Pt is heat treated and ordered. The enhanced sensitivity of the Faraday rotation measurements compared to the magnetic dichroism measurements at the K edges of transition metals are reported on.
