Abstract
The transport properties of disordered concentrated ferromagnetic NiT alloys, with T=Cr, Fe, Co or Cu, are analysed at low temperatures within the framework of the two-current model. A theoretical expression for the spontaneous resistivity anisotropy is derived using the method of the force-force correlation functions. Starting from the two-current formula for the electrical resistivity the sub-band resistivities rho spin up and rho spin down are calculated approximately. The results are compared with CPA calculations.
