Dispersion and lifetimes of magnons in non-collinear magnets from time dependent density functional theory
David Eilmsteiner, Arthur Ernst, PaweÅ A. Buczek
We investigate the spin dynamics of the non-collinear kagome triangular anti-ferromagnet MnRh using linear response time-dependent density functional theory. To this end, we pr…
Dynamical magnetic susceptibility of non-collinear magnets: A novel KKR-based ab initio scheme and its application
David Eilmsteiner, Arthur Ernst, PaweÅ A. Buczek
A novel implementation of the linear response time-dependent density functional theory addressing spin excitations in non-collinear magnets based on the Korringa-Kohn-Rostoker Gree…
Loss of altermagnetic order and smooth restoration of Kramers' spin degeneracy with increasing temperature in CrSb and MnTe
Christopher D. Woodgate, Nabil Menai, Arthur Ernst +1
We describe how thermally induced spin fluctuations modify the electronic structures of two prototypical altermagnets, CrSb and MnTe, via application of the disordered local moment…
High temperature Neel skyrmions in simple ferromagnets
Peng Wang, Rana Saha, Holger L. Meyerheim +10
A wide variety of chiral non-collinear spin textures have been discovered and have unique properties that make them highly interesting for technological applications. However, many…
Exploring non-collinear magnetic ground states in tetragonal Mn-based Heusler compounds
Jorge Cardenas-Gamboa, Edouard Lesne, Arthur Ernst +3
Heusler compounds constitute a large family of intermetallic materials notable for their wide variety of properties such as magnetism, multi-ferroicity, nontrivial band topology, s…
