      abstract     = {Finite-temperature magnetic properties of half-metallic
                      materials are investigated on the basis of the
                      first-principles Korringa-Kohn-Rostoker Green's function
                      method. Influences of spin-wave excitations on the
                      electronic structure are examined in the framework of the
                      coherent potential approximation. The calculations show that
                      the half-metallicity is easily destroyed due to an
                      appearence of low-energy electron excited states in the
                      minority-spin band gap at finite temperature. On the other
                      hand, calculated dc conductivity shows that the $100\%$
                      spin-polarized conduction occurring in half-metallic
                      materials hardly deteriorates even in such a temperature.},
