A theoretical description of spin resolved transport — •Stephan Lowitzer1, Diemo Ködderitzsch1, Hubert Ebert1, and Julie B. Staunton21Department Chemie und Biochemie, LMU München, Butenandtstraße 11, 81377 München — 2Department of Physics, University of Warwick, Coventry CV4 7AL, UK

Spin resolved transport became during the last years a fast growing field of interest for many theoretical working groups. We present an approximative scheme to calculate the spin decomposed conductivity within the Kubo-Greenwood formalism. The electronic structure calculations are based on the fully relativistic Korringa-Kohn-Rostoker (KKR) band structure method in connection with the coherent potential approximation (CPA) alloy theory. To demonstrate the reliability of our approach we apply this formalism to Fe1−xCrx and the diluted magnetic semiconductor system (DMS) Ga1−xMnxAs.
