Temperature dependence of spin-model parameters in antiferromagnets
Levente Rózsa, Unai Atxitia
The temperature dependence of mesoscopic spin-model parameters is derived in two-sublattice antiferromagnetically aligned systems based on Green's function theory. It is found that…
Electron-phonon mediated spin-flip as driving mechanism for ultrafast magnetization dynamics in 3 ferromagnets
Theodor Griepe, Unai Atxitia
Despite intense experimental effort, theoretical proposals and modeling approaches, a lack of consensus exists about the intrinsic mechanisms driving ultrafast magnetization dynami…
Breaking through the Mermin-Wagner limit in 2D van der Waals magnets
Sarah Jenkins, Levente Rozsa, Unai Atxitia +3
The Mermin-Wagner theorem states that long-range magnetic order does not exist in one- or two-dimensional (2D) isotropic magnets with short-ranged interactions. The theorem has bee…
Temperature-dependent critical spin-orbit field for orthogonal switching in antiferromagnets
R. Rama-Eiroa, R. M. Otxoa, U. Atxitia
The discovery of current-induced spin-orbit torque (SOT) orthogonal reorientation, also known as orthogonal switching, of metallic MnAu and CuMnAs has opened the door for ultra…
Robust magnetic order upon ultrafast excitation of an antiferromagnet
Sang-Eun Lee, Yoav William Windsor, Alexander Fedorov +8
The ultrafast manipulation of magnetic order due to optical excitation is governed by the intricate flow of energy and momentum between the electron, lattice and spin subsystems. W…
Bridging atomistic spin dynamics methods and phenomenological models of single pulse ultrafast switching in ferrimagnets
Florian Jakobs, Unai Atxitia
We bridge an essential knowledge gap on the understanding of all-optical ultrafast switching in ferrimagnets; namely, the connection between atomistic spin dynamics methods and mac…
