First-principles relativistic theory of the magnetic response of paramagnetic metals: Application to yttrium and scandium
2003
Physical Review B (Condensed Matter)
We describe a first-principles theoretical formalism for the magnetic response of paramagnetic metals in which all relativistic effects such as spin-orbit coupling are included. In particular, the easy axis and dependence upon wave vector q of the paramagnetic spin susceptibility (q) can be calculated. To illustrate we apply the method to two transition metals, yttrium and scandium. In each case we find (q) to peak at a wave vector qϭ(0,0,0.57)/c, coincident with a Fermi surface nesting vector,
