Zusammenfassung: 
The phenomena of magnetic circular and linear dichroism in the angular distribution (MCDAD and MLDAD) of photoelectrons manifest themselves in different photoelectron intensities in the related parts of their spectra when the sample is remanently magnetized in opposite directions. In combination with the experimental results carried out at the storage ring BESSY in Berlin, new fully relativistic photoemission calculations have been performed under the consideration of fully circularly and linearly polarized radiation in the soft-x-ray region. Were, we present the energetic dependence and the relationship between MCDAD and MLDAD in the energy range from hv=90 to 175 eV. The physical origin of both phenomena is analyzed in detail with respect to the hybridization of the Fe 3p multiplet and the dynamics in this process is discussed. [S0163-1829(99)00140-X].
