Abstract A new variational-principle density-functional theory for the spin susceptibility χ has been used to calculate χ for Li, Na, K, Rb, and Cs and its volume dependence for Li and Na. The theory simultaneously includes lattice, core electron, and many-body effects. The exchange-correlation functionals are treated in the local spin density approximation. The single-particle electron states are treated self-consistently. The cubic symmetry for the Fermi-surface electrons was included by using a muffin-tin approximation in the augmented-plane-wave method. The good agreement between the results and recent experiments indicates that the local spin density approximation is valid for simple metals, and also suggests that the exchange-correlation enhancement of χ for the uniform electron system saturates at very low densities.
