Polarization-modulation technique with diamond phase retarder to improve the accuracy of XMCD measurements ble to the FI method mentioned above, and therefore suffer from similar requirements on beam stability. We will show the XMCD spectrum measured at the Fe K-edge in CoFe204, using this polarization-modulation (PM) technique. The spectrum shows the advantage in higher signal-to-noise ratio over the conventional FI method.
