Abstract：
Magnetic circular dichroism spectroscopy using hard X-rays was established at 1W1B beamline and XAFS experimental station of Beijing Synchrotron Radiation Facility. The left and right circularly polarized X-rays were obtained by converting the incident linearly polarized X-rays using a phase retarder made of diamond crystal working at Laue geometry．XMCD spectra of disordered Pt-Fe alloys at Pt L₂ and L₃ edge were measured in transmission mode and a dramatic XMCD signal was observed. The performance of this method was evaluated and demonstrated.
