Query: Spin-polarized transport in ferromagnetic multilayers: An
  unconditionally convergent FEM integrator   We propose and analyze a decoupled time-marching scheme for the coupling of
the Landau-Lifshitz-Gilbert equation with a quasilinear diffusion equation for
the spin accumulation. This model describes the interplay of magnetization and
electron spin accumulation in magnetic and non-magnetic multilayer structures.
Despite the strong nonlinearity of the overall PDE system, the proposed
integrator requires only the solution of two linear systems per time-step.
Unconditional convergence of the integrator towards weak solutions is proved.
