摘要：

Magnetic X-ray circular dichroism (MCD) spectra at the Pt L-2 and L-3 absorption edges of several Pt intermetallic compounds are evaluated based on first-principles electronic structure calculations. The results are in good agreement with recent MCD experiments, reproducing well the shape of the observed spectra as well as their sign and relative size.
