摘要：

X-ray Faraday rotation-the dispersive analogue of x-ray magnetic circular dichroism-has been measured near the platinum L edges of ferromagnetic disordered Fe3Pt using a simple new technique. We show that fractional x-ray intensity changes on magnetization reversal scale directly with the Faraday signal. The validity of the new approach as an alternative method for obtaining circular dichroism spectra is verified by performing simultaneous Faraday rotation and dichroism measurements, and comparing the results with Kramers-Kronig transforms.
