ABSTRACT
The Disordered Local Moment Method (DLM) is based on the idea that in itinerant metallic magnets, on a certain time scale ζ, which is small as compared to the characteristic time of spin fluctuations, but longer than the electron hopping times, the spin orientations of the electrons leaving an atomic site are sufficiently correlated with those arriving such that a nonzero magnetization exists when the appropriate quantity is averaged over ζ. In this scheme the magnetic excitations are modeled [1] - [4] by associating local spin-polarization axes with all lattice sites and the orientations {eˆi} vary very slowly on the time-scale of the electronic motions. The approach given below is again fully relativistic.
