Query: Spin-spiral formalism based on the multiple scattering Green's function
  technique with applications to ultrathin magnetic films and multilayers   Based on the Korringa-Kohn-Rostoker Green's function technique we present a
computational scheme for calculating the electronic structure of layered
systems with homogeneous spin-spiral magnetic state. From the self-consistent
non-relativistic calculations the total energy of the spin-spiral states is
determined as a function of the wave vector, while a relativistic extension of
the formalism in first order of the spin-orbit coupling gives an access to the
effect of the Dzyaloshinskii-Moriya interactions. We demonstrate that the newly
developed method properly describes the magnetic ground state of a Mn monolayer
on W(001) and that of a Co monolayer on Pt(111). The obtained spin-spiral
energies are mapped to a classical spin model, the parameters of which are
compared to those calculated directly from the relativistic torque method. In
case of the Co/Pt(111) system we find that the isotropic interaction between
the Co atoms is reduced and the Dzyaloshinskii-Moriya interaction is increased
when capped by a Ru layer. In addition, we perform spin-spiral calculations on
Ir/Fe/Co/Pt and Ir/Co/Fe/Pt multilayer systems and find a spin-spiral ground
state with very long wavelength due to the frustrated isotropic couplings
between the Fe atoms, whereas the Dzyaloshinskii-Moriya interaction strongly
depends on the sequence of the Fe and Co layers.
