Fe 2p photoemission magnetic dichroism with linearly polarized synchrotron radiation and with unpolarized Al K alpha radiation

We report on the measurements and analysis of Fe 2p magnetic dichroism in the angular distribution of the photoelectrons from remanently magnetized Fe(100)surfaces with unpolarized, monochromatized Al K alpha X-rays of 1486 eV energy (MDAD) and with linearly polarized synchrotron radiation of energy 800 eV (LMDAD). The two experiments verify the atomic photoionization model of (L)MDAD including the dichroism effect between field-averaged experiments of different chirality.
