High-transition temperature (high-T c) superconductivity in the iron pnictides or
chalcogenides emerges from the suppression of the static antiferromagnetic order in their …

The iron-based superconductors that contain FeAs layers as the fundamental building block
in the crystal structures have been rationalized in the past using ideas based on the Fermi …

We theoretically investigate a nonlinear spin Hall effect in PT-symmetric antiferromagnetic
metals, which serve as an efficient spin current generator. We elucidate that an emergent …

This paper is a contribution to the joint Physical Review Applied and Physical Review
Materials collection titled Two-Dimensional Materials and Devices. Fe 5− x GeTe 2 is a van …

We theoretically investigate an intrinsic nonlinear anomalous Hall effect (INAHE) in space-
time (PT) symmetric antiferromagnetic metals. The INAHE is characterized by an asymmetric …

A magnetic toroidal moment is a fundamental electronic degree of freedom in the absence of
both spatial inversion and time-reversal symmetries and gives rise to novel multiferroic and …

The nature of an electric ferroaxial moment characterizing a time-reversal-even axial-vector
quantity is theoretically investigated under magnetic orderings. We clarify that a vortex spin …

Previous experimental results have shown important differences between iron selenide and
arsenide superconductors which seem to suggest that the high-temperature …

Superconductivity in iron selenides has experienced a rapid growth, but not without major
inconsistencies in the reported properties. For alkali-intercalated iron selenides, even the …

Magnetic toroidicity is an uncommon type of magnetic structure in solid-state materials.
Here, we experimentally demonstrate that collinear spins in a material with R-3 lattice …
