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…
Zero-field magnetic skyrmions in exchange-biased ferromagnetic-antiferromagnetic bilayers
M. Pankratova, O. Eriksson, A. Bergman
We report on the stabilization of ferromagnetic skyrmions in zero external magnetic fields, in exchange-biased systems composed of ferromagnetic-antiferromagnetic (FM-AFM) bilayers…
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…
