Abstract
A model binary alloy AxB1-x which exhibits long-range order is considered. The electronic transport is treated in the coherent potential approximation (CPA). The tensor of the electrical conductivity calculated from the Kubo-Greenwood formula depends on a long-range order parameter. The strongest dependence takes place for x=0.5. Also the numerical results indicate the possibility that the conductivity may increase or decrease with temperature according to alloy composition.Keywords
