摘要： By means of the renormalized vertex procedure for the motion Green's function developed by the au-thors, the vertex function of magnetic alloys, based on the s-d exchange interaction, is solved exactly and the corresponding Hall conductivity tensors are obtained. It is found that the renormalized modification of the conductivity is very important in the cases of not too weak extermal magnetic field and slow relexaction time.
