## Abstract This paper gives an overview of the recent studies of spin dynamics in diluted magnetic semiconductor heterostructures based on (Zn,Mn)Se and (Cd,Mn)Te. The spin dynamics is controlled by energy and spin transfer between systems of magnetic ions, lattice (phonon system) and free carrier
The spin correlation density of conduction electrons with an impurity spin is calculated at T->O for the degenerate orbital case of the Anderson model on the basis of the }ramada and Yosida theory. The leading term at long distance falls off as r-S[ I + cos (2kpr + 28)], keeping a negative sign. For
