Circularly polarized X‐rays produced by a diamond X‐ray phase retarder of thickness 0.5 mm in the Laue transmission configuration have been used for recording X‐ray magnetic circular dichroism (XMCD) on the bending‐magnet beamline BM25A (SpLine) at the ESRF. Field reversal and helicity reversal techniques have been used to carry out the measurements. The performance of the experimental set‐up has been demonstrated by recording XMCD in the energy range from 7 to 11 keV.
