Basic theoretical models describing anomalous kinetic phenomena in disordered ferromagnetic alloys of transition metals are considered. It is shown that qualitative agreement with experimental data can be achieved with an account of the non-Born-like character of carrier scattering in a random potential. A methodology for calculating anomalous kinetic coefficients for a coherent potential is described. Results are given on calculations of the density dependence of the anomalous Hall effect for real alloy systems using realistic models of the electron density of the states.

Anomalous Hall effect in disordered ferromagnetic alloys of the transition metals

The concentration dependence of the off-diagonal component of the electroconductivity tensor and that of the average magnetic moment are calculated for PdFe, PdCo, and PdNi alloys in the coherent potential approximation (CPA). These calculations are based on realistic models of the component densities of states (DOS's). Experimental and theoretical results are compared.
