Abstract
We discuss the current status of density functional spin dynamics and exchange interactions theory in metallic magnets. The connection between linear response technique and Heisenberg model is analyzed. The relation between the general “inverse susceptibility” approach and “long wavelength” approximation is established. The smallnes parameter is estimated for ferromagnetic transition metals.
