Interplay of spin-phonon coupling in FeSe with pressure and isoelectronic (S/Te) substitution
Abyay Ghosh, Piotr Chudzinski, Myrta Grüning
In several studies, magnetism has been shown to strongly influence the properties of the iron chalcogenide compound \ce{FeSe}. In our previous work [Phys. Rev. Res. 6(4), 043154 (2…

Generalized incommensurability: the role of anomalously strong spin-orbit coupling for the spin ordering in a quasi-2D system, FeSe
Piotr Chudzinski, Abyay Ghosh, Myrta Gruening
We study 2D spin and orbital systems, in a classical limit, in a regime where their coupling is so strong that orbital fluctuations are able to change sign of spin-exchange. Our ai…
