EN

The intermetallic compound Co_2MnSi is halfmetallic, but the structure of real samples is often affected by antisite disorder. The influence of disorder on transport properties is examined by ab initio calculations and is found to be more significant in thin Co_2MnSi slabs sandwiched by metallic leads than in the bulk compound.
