abstract = {The half-metallic Heusler compound Co2MnSi is a very
attractive material for spintronic devices because it
exhibits very high tunnelling magnetoresistance ratios. This
work reports on a spectroscopic investigation of thin
Co2MnSi films as they are used as electrodes in magnetic
tunnel junctions. The investigated ̄lms exhibit a remanent
in-plane magnetization with a magnetic moment of about 5 uB
when saturated, as expected. The low coercive field of only
4 mT indicates soft magnetic behavior. Magnetic dichroism in
emission and absorption was measured at the Co and Mn 2p
core levels. The photoelectron spectra were excited by
circularly polarized hard X-rays with an energy of 6 keV and
taken from the remanently magnetized film. The soft X-ray
absorption spectra were taken in an induction ̄eld of 4 T.
Both methods yielded large dichroism effects. An analysis
reveals the localized character of the electrons and
magnetic moments attributed to the Mn atoms, whereas the
electrons related to the Co atoms contribute an itinerant
part to the total magnetic moment.},
