Temperature dependence of spin-model parameters in ferrimagnets
Marta Yanguas, José M. Lendínez, Theodor Griepe +3
We compute the temperature dependence of effective spin-model parameters in two-sublattice ferrimagnets with antiparallel and inequivalent sublattice magnetizations using Green's-f…
Universal theory of domain-wall width in multi-sublattice Heisenberg magnets
José M. Lendínez, Marta Yanguas, Theodor Griepe +4
We propose a universal expression for the domain-wall width in generic multi-sublattice Heisenberg magnets, applicable to ferro-, antiferro-, and ferrimagnetic orders. The result f…
Spin Inertia as a Source of Topological Magnons: Chiral Edge States from Coupled Precession and Nutation
Subhadip Ghosh, Mikhail Cherkasskii, Ritwik Mondal +2
Spin inertia has been demonstrated to give rise to high-frequency nutational excitations beyond the conventional low-frequency precessional modes. Here, we demonstrate that the hyb…
Anisotropic skyrmion liquid phase
Daniel Schick, Tim Matthies, Thomas Mutschler +2
The nature of the melting transition in two-dimensional systems of particles has attracted considerable research attention since the development of Kosterlitz-Thouless-Halperin-Nel…
