A new internet‐based synchrotron experiment for students is presented. A polarimeter and computer software have been developed for measuring via the internet the X‐ray magnetic circular dichroism of PtFe around its Pt L II and L III absorption edges. From the experiment, students can examine the X‐ray magnetic circular dichroism of a thin PtFe foil utilizing circular‐polarized synchrotron radiation emitted by the superconducting asymmetric wiggler at the synchrotron radiation source DELTA of the University of Dortmund.
