      abstract     = {The magnitude of the spin polarization at the Fermi level
                      of ferromagnetic materials at room temperature is a key
                      property for spintronics. Investigating the Heusler compound
                      Co2MnSi, a value of $93\%$ for the spin polarization has
                      been observed at room temperature, where the high spin
                      polarization is related to a stable surface resonance in the
                      majority band extending deep into the bulk. In particular,
                      we identified in our spectroscopical analysis that this
                      surface resonance is embedded in the bulk continuum with a
                      strong coupling to the majority bulk states. The resonance
                      behaves very bulklike, as it extends over the first six
                      atomic layers of the corresponding (001) surface. Our study
                      includes experimental investigations, where the bulk
                      electronic structure as well as surface-related features
                      have been investigated using spin-resolved photoelectron
                      spectroscopy (SR-UPS) and for a larger probing depth
                      spin-integrated high energy x-ray photoemission spectroscopy
                      (HAXPES). The results are interpreted in comparison with
                      first-principles band structure and photoemission
                      calculations which consider all relativistic, surface, and
                      high-energy effects properly.},
