DOI: 10.1016/j.jmmm.2018.08.034

Abstract: Abstract A combined dynamics for the spin and lattice degrees of freedom is proposed. For that we couple a Heisenberg spin Hamiltonian via a distance dependent exchange integral and an anisotropic correction to the lattice,… read more here.

DOI: 10.1038/s41567-018-0053-8

Abstract: As a fundamental parameter in magnetism, the phenomenological Gilbert damping constant α determines the performance of many spintronic devices. For most magnetic materials, α is treated as an isotropic parameter entering the Landau–Lifshitz–Gilbert equation. However,… read more here.
