Exciton-induced magnons carrying orbital angular momentum in CrI3
Martin Pavelka, Vishal Shokeen, Ruslan Chulkov +15
Magnons are collective spin excitations that contain and transport spin angular momentum in magnetic materials. It has been suggested that they can also carry orbital angular momen…
Ultrafast demagnetization dynamics of 4f antiferromagnets
Maryna Pankratova, Vladislav Borisov, Danny Thonig +6
We study the ultrafast demagnetization dynamics of LnRhSi (Ln Pr, Nd, Sm, Gd, Tb, Dy, Ho) antiferromagnets (AFM) after excitation by a laser pulse, using a combination…
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…
Tuning order-by-disorder multiferroicity in CuO by doping
J. Hellsvik, M. Balestieri, T. Usui +8
The high Curie temperature multiferroic compound, CuO, has a quasidegenerate magnetic ground state that makes it prone to manipulation by the so called ``order-by-disorder'' mechan…
