      abstract     = {There is broad consensus that magnetite (Fe$_3$O$_4$) is a
                      promising material for spintronics applications due to its
                      high degree of spin polarization at the Fermi level.
                      However, previous attempts to measure the spin polarization
                      by spin-resolved photoemission spectroscopy have been
                      hampered by the use of low photon energies resulting in high
                      surface sensitivity. The surfaces of magnetite, though, tend
                      to reconstruct due to their polar nature, and thus their
                      magnetic and electronic properties may strongly deviate from
                      each other and from the bulk, dependent on their orientation
                      and specific preparation. In this study, we determine the
                      intrinsic—i.e., bulk—spin polarization of magnetite by
                      spin-resolved photoelectron spectroscopy on (111)-oriented
                      thin films, epitaxially grown on ZnO(0001), with hard
                      x-rays, making it a truly bulk-sensitive probe. This becomes
                      possible by using a novel, specially adapted momentum
                      microscope, featuring time-of-flight energy recording and an
                      imaging spin-filter.},
