Abstract
- The temperature dependence of the spin polarization of half-metallic ferromagnets is analyzed. A unitary spinor transformation indicates that the corresponding spin mixing goes beyond finite-temperature smearing of the Fermi level, leading to a nonzero density of states in the gap of the insulating spin channel and as a consequence half-metallic ferromagnetism is limited to zero temperature.
