A Stoner model for transition metals at T = 0 is derived using the Hohenberg-Kohn-Sham spin-density-functional formalism in the local-spin-density (LSD) approximation. The applicability of the LSD approximation is discussed and support for using it for transition metals and magnetic properties is presented. The additional approximations required in the derivation of a Stoner model are shown to be small. Results for the Stoner parameter are given, trends are discussed, and some applications of the model are reviewed.

We shall finally consider the spin susceptibility, which in Stoner theory [3] is given by
