abstract = {Knowledge of the spin-dependent electronic structure at
surfaces and interfaces plays an increasingly important role
when assessing possible use of novel magnetic materials for
spintronic applications. It is shown that spin- and
angle-resolved photoelectron spectroscopy together with ab
initio electronic structure methods provides a full
characterization of the surface electronic structure of
ferromagnetic MnSb(0 0 0 1). Two different surface
reconstructions have been compared in spin- and
angle-resolved valence-band photoemission. For annealing at
elevated temperatures, the ( 1 x 1)-structure transforms
into 2 x 2 and a majority-spin peak appears at - 1.7 eV
inside a majority-spin bulk band gap at the surface
Brillouin zone centre. Its sensitivity to oxygen supports an
interpretation as magnetic compound surface state. Local
spin density calculations predict at the same energy (- 1.75
eV) a prominent d(z)2 surface state of majority spin for ( 1
x 1)- Mn terminated MnSb(0 0 0 1) but no such feature for (
1 x 1)-Sb termination. The calculation shows that neither
the bulk nor the surface is half-metallic, in agreement with
the expectation for the hexagonal NiAs structure.},
