Magnetically driven suppression of nematic order in an iron-based superconductor.
TLDR
The observation by neutron powder diffraction of an additional fourfold-symmetric phase in Ba1-xNaxFe2As2 close to the suppression of SDW order is reported, which is consistent with the predictions of magnetically driven models of nematic order.
A high-temperature ferromagnetic topological insulating phase by proximity coupling
TLDR
The topological magneto-electric response originating in such an engineered topological insulator could allow efficient manipulation of the magnetization dynamics by an electric field, providing an energy-efficient topological control mechanism for future spin-based technologies.
Double-Q spin-density wave in iron arsenide superconductors
Elucidating the nature of the magnetic ground state of iron-based superconductors is of paramount importance in unveiling the mechanism behind their high-temperature superconductivity. Until…
Erratum: Preemptive nematic order, pseudogap, and orbital order in the iron pnictides (Physical Review B - Condensed Matter and Materials Physics)
Non-local dxy nematicity and the missing electron pocket in FeSe
The origin of spontaneous electronic nematic ordering provides important information for understanding iron-based superconductors. Here, we analyze a scenario where the d x y orbital strongly…
Preemptive nematic order, pseudogap, and orbital order in the iron pnictides
Starting from a microscopic itinerant model, we derive and analyze the effective low-energy model for collective magnetic excitations in the iron pnictides. We show that the stripe magnetic order is…
Magnetism, superconductivity, and pairing symmetry in iron-based superconductors
We analyze antiferromagnetism and superconductivity in novel Fe-based superconductors within the itinerant model of small electron and hole pockets near 0,0 and ,. We argue that the effective…
Theory of magnetic excitations in iron-based layered superconductors
Based on the effective four-band model we analyze the spin response in the normal and superconducting states of the Fe-pnictide superconductors. While the normal state spin excitations are dominated…
Enhancement of the Superconducting Gap by Nesting in CaKFe_{4}As_{4}: A New High Temperature Superconductor.
TLDR
These results provide strong support for the multiband character of superconductivity in CaKFe_{4}As_{4}, in which Cooper pairing forms on the electron and the hole bands interacting via a dominant interband repulsive interaction, enhanced by band nesting.
Interplay of magnetic and structural transitions in iron-based pnictide superconductors
The interplay between the structural and magnetic phase transitions occurring in the Fe-based pnictide superconductors is studied within a Ginzburg-Landau approach. We show that the magnetoelastic…
