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…
Strain-Induced Decoupling Drives Gold-Assisted Exfoliation of Large-Area Monolayer 2D Crystals
Jakob Ziewer, Abyay Ghosh, Michaela Hanušová +5
Gold assisted exfoliation (GAE) is a groundbreaking mechanical exfoliation technique, producing centimeter scale single crystal monolayers of 2D materials. Such large, high quality…
A first-principles study and mesoscopic modeling of two-dimensional spin and orbital fluctuations in FeSe
Abyay Ghosh, Piotr Chudzinski, Myrta Grüning
We calculated the structural, electronic and magnetic properties of FeSe within density-functional theory at the generalized gradient approximation level. First, we studied how the…
Neutron spin resonance in a quasi-two-dimensional iron-based superconductor
Wenshan Hong, Linxing Song, Bo Liu +15
Magnetically mediated Cooper pairing is generally regarded as a key to establish the unified mechanism of unconventional superconductivity. One crucial evidence is the neutron spin…
Neutron spin resonance in the 112-type iron-based superconductor
Tao Xie, Dongliang Gong, Haranath Ghosh +9
We use inelastic neutron scattering to study the low-energy spin excitations of 112-type iron pnictide CaLaFeNiAs with bulk superconductiv…
Electronic origin of structural transition in 122 Fe based superconductors
Haranath Ghosh, Smritijit Sen, Abyay Ghosh
Direct quantitative correlations between the orbital order and orthorhombicity is achieved in a number of Fe-based superconductors of 122 family. The former (orbital order) is calc…
