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.}, keywords = {J (WoSType)}, cin = {IAS-1 / PGI-1}, ddc = {530}, cid = {I:(DE-Juel1)IAS-1-20090406 / I:(DE-Juel1)PGI-1-20110106}, pnm = {Grundlagen für zukünftige Informationstechnologien}, pid = {G:(DE-Juel1)FUEK412}, shelfmark = {Physics, Condensed Matter}, typ = {PUB:(DE-HGF)16}, UT = {WOS:000305783500005}, doi = {10.1103/PhysRevB.85.224437}, url = {https://juser.fz-juelich.de/record/22312}, }
