	abstract = {The spin-orbit interaction can cause a nonvanishing density of states (DOS) within the minority-spin band gap of half metals around the Fermi level. We examine the magnitude of the effect in Heusler alloys, zinc-blende half metals, and diluted magnetic semiconductors, using first-principles calculations. We find that the ratio of spin-down to spin-up DOS at the Fermi level can range from below 1\% (e.g., 0.5\% for NiMnSb) over several percents {[}4.2\% for (Ga,Mn)As] to 13\% for MnBi. This gives a spin polarization P at E-F ranging from above 99\% for NiMnSb to Papproximate to92\% for (Ga,Mn)As and to Papproximate to77\% for MnBi.},
