Spin Reorientation Driven Renormalization of Spin-Phonon Coupling in FeGeTe
Riju Pal, Md. Nur Hasan, Chumki Nayak +9
Quasi-2D van der Waals ferromagnet FeGeTe, featuring the simultaneous presence of high Curie temperature ( K) and a spin-reorientation transition a…
Dynamical electronic correlation and chiral magnetism in van der Waals magnet Fe4GeTe2
Md. Nur Hasan, Nastaran Salehi, Felix Sorgenfrei +7
Among the quasi-2D van der Waals magnetic systems, Fe4GeTe2 imprints a profound impact due to its near-room temperature ferromagnetic behaviour and the complex magnetothermal phase…
Hybrid micromagnetic and atomistic modeling of magnetization dynamics induced by engineered defects
Nastaran Salehi, Olle Eriksson, Johan Hellsvik +1
This study presents a 3D version of multiscale approach for investigating magnetization dynamics in multiscale, hybrid micromagnetic-atomistic simulations. The present work introdu…
Spin-lattice couplings in ferromagnets: analysis from first-principles
I. P. Miranda, M. Pankratova, M. Weißenhofer +8
Magnetoelasticity plays a crucial role in numerous magnetic phenomena, including magnetocalorics, magnon excitation via acoustic waves, and ultrafast demagnetization/Einstein-de Ha…
Quantum spin systems: toroidal classification and geometric duality
Vahid Azimi-Mousolou, Anders Bergman, Anna Delin +4
Toroidal classification and geometric duality in quantum spin systems is presented. Through our classification and duality, we reveal that various bipartite quantum features in mag…
Stability and dynamics of magnetic skyrmions in FM/AFM heterostructures

Tuning of the ultrafast demagnetization by ultrashort spin polarized currents in multi-sublattice ferrimagnets
Deeksha Gupta, Maryna Pankratova, Matthias Riepp +11
Femtosecond laser pulses can be used to induce ultrafast changes of the magnetization in magnetic materials. Several microscopic mechanisms have been proposed to explain the observ…
Quantum analog of Landau-Lifshitz-Gilbert dynamics
Yuefei Liu, Ivan P. Miranda, Lee Johnson +7
The Landau-Lifshitz-Gilbert (LLG) and Landau-Lifshitz (LL) equations play an essential role for describing the dynamics of magnetization in solids. While a quantum analog of the LL…
Prediction of a new efficient permanent magnet SmCoNiFe3
P. Söderlind, A. Landa, I. L. M. Locht +7
We propose a new efficient permanent magnet, SmCoNiFe3, that is a breakthrough development of the well-known SmCo5 prototype. More modern neodymium magnets of the Nd-Fe-B type have…
Magnetism and ultra-fast magnetization dynamics of Co and CoMn alloys at finite temperature
R. Chimata, E. K. Delczeg-Czirjak, A. Szilva +9
Temperature-dependent magnetic experiments like pump-probe measurements generated by a pulsed laser have become a crucial technique for switching the magnetization in the picosecon…
