X-ray magnetic circular dichroism (XMCD) is a powerful tool for element-selective observation of magnetic structures in ferromagnets, but theoretical analysis of the microscopic origin of angle-dependent XMCD spectra is lacking. We have developed an angle-dependent XMCD calculation method using first-principles calculations. In this presentation, we will discuss microscopic origins of changes in the angle-dependent XMCD spectral on the basis of electronic structures and p-d transition probabilities in L1₀-type FePt and CoPt alloys.
