A variational formulation of the time-dependent linear response based
on the Sternheimer method is developed in order to make practical ab initio
calculations of dynamical spin susceptibilities of solids. Using gradient
density functional and a muffin-tin-orbital representation. The efficiency
of the approach is demonstrated by applications to selected magnetic and
strongly paramagnetic metals. The results are found to be consistent with
experiment and are compared with previous theoretical calculations.
