      abstract     = {We present a first-principles Study of the unreconstructed
                      (001) surfaces of the half-metallic ferromagnet NiMnSb. Both
                      terminations (MnSb and Ni) are considered. We find that
                      half-metallicity is lost at the surfaces. After a discussion
                      of the geometric relaxations and the spin-polarized surface
                      band structure, we focus on topography images which are
                      expected to be found with spin-polarized scanning tunnelling
                      microscopy. For the MnSb-terrninated surface we find that
                      only the Sb atoms are visible, reflecting a geometric
                      buckling caused by relaxations. For the Ni-terminated
                      surface we find a strong contrast between the images of
                      forward and reverse tip-sample-bias of 0.5 eV, as well as a
                      stripe-like image for reverse bias. We interpret these
                      findings in terms of highly directional Surface states which
                      are formed in the spin-down gap region.},
