Role of temperature-dependent spin model parameters in ultra-fast magnetization dynamics
A. Deák, D. Hinzke, L. Szunyogh +1
In the spirit of multi-scale modelling magnetization dynamics at elevated temperature is often simulated in terms of a spin model where the model parameters are derived from first…
Thermally induced magnon accumulation in two-sublattice magnets
Ulrike Ritzmann, Denise Hinzke, Ulrich Nowak
We present a temperature dependent study of the thermal excitation of magnonic spin currents in two-sublattice magnetic materials. Using atomistic spin model simulations, we study…
Propagation of Thermally Induced Magnonic Spin Currents
Ulrike Ritzmann, Denise Hinzke, Ulrich Nowak
The propagation of magnons in temperature gradients is investigated within the framework of an atomistic spin model with the stochastic Landau-Lifshitz-Gilbert equation as underlyi…
Roles of heating and helicity in ultrafast all-optical magnetization switching in TbFeCo
Xianyang Lu, Xiao Zou, Denise Hinzke +10
Using time-resolved magneto-optical Kerr effect (TR-MOKE) method, helicity-dependent all-optical magnetization switching (HD-AOS) is observed in ferrimagnetic TbFeCo films. The the…
Magnetic field control of the spin Seebeck effect
Ulrike Ritzmann, Denise Hinzke, Andreas Kehlberger +3
The origin of the suppression of the longitudinal spin Seebeck effect by applied magnetic fields is studied. We perform numerical simulations of the stochastic Landau-Lifshitz-Gilb…
Multiscale modeling of ultrafast element-specific magnetization dynamics of ferromagnetic alloys
D. Hinzke, U. Atxitia, K. Carva +4
A hierarchical multiscale approach to model the magnetization dynamics of ferromagnetic ran- dom alloys is presented. First-principles calculations of the Heisenberg exchange integ…
