The angular dependent K ‐edge X‐ray magnetic circular dichroism (XMCD) spectra based on the semi‐relativistic full multiple scattering theory are discussed, where 2‐spinor formalism is used to describe spin‐orbit coupling. So far most of theoretical approaches have been limited to the simplest case where the circularly polarized X‐ray propagation coincides with the direction of the magnetic field. Here we discuss more general cases, using the above theoretical approaches. We separately discuss atomic, single and full multiple scattering XMCD spectra; in particular anisotropic features of them are studied in detail.
