Gilbert damping for epitaxial Co2FeAl Heusler alloy films was investigated by analyzing the data of ferromagnetic resonance measured at the frequency of 2.20 GHz as discussed by the authors.Abstract:
Gilbert damping for the epitaxial Co2FeAl Heusler alloy films was investigated. Gilbert damping constant for the films was evaluated by analyzing the data of ferromagnetic resonance measured at the frequency of 2–20 GHz. Gilbert damping constant for the film without annealing was rather large, while it decreased remarkably with postannealing. Gilbert damping constant for the film annealed at 600 °C was ≃0.001. These behavior of Gilbert damping constant can be well explained by the fact that the density of states calculated from first principles decreases with increasing the degree of B2 order.read more

Walter Kohn,Norman Rostoker +1 more
TL;DR: In this article, the problem of solving the Schrodinger equation in a periodic lattice is studied from the point of view of the variation-iteration method, which leads to a very compact scheme if the potential $V(r)$ is spherically symmetrical within the inscribed spheres of the atomic polyhedra and constant in the space between them.

On the Landau-Lifshitz relaxation in ferromagnetic metals
TL;DR: In this paper, it was shown that the scattering of ferromagnetic band-electrons by phonons combined with the spin-orbit interaction caused magnetic relaxation of the Landau-Lifshitz-Gilbert type.
