Chiral photocurrent in parity-violating magnet and enhanced response in topological antiferromagnet

H Watanabe, Y Yanase - Physical Review X, 2021 - APS
Rectified electric current induced by irradiating light, a so-called photocurrent, is an
established phenomenon in optoelectronic physics. In this paper, we present a …

Group-theoretical classification of multipole order: Emergent responses and candidate materials

H Watanabe, Y Yanase - Physical Review B, 2018 - APS
The multipole moment is an established concept of electrons in solids. Entanglement of spin,
orbital, and sublattice degrees of freedom is described by the multipole moment, and …

Nonlinear spin Hall effect in -symmetric collinear magnets

S Hayami, M Yatsushiro, H Kusunose - Physical Review B, 2022 - APS
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 …

Ferroaxial moment induced by vortex spin texture

S Hayami - Physical Review B, 2022 - APS
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 …

The fourth ferroic order: Current status on ferrotoroidic materials

S Gnewuch, EE Rodriguez - Journal of Solid State Chemistry, 2019 - Elsevier
We review the topic of ferrotoroidicty and the inorganic solids proposed to exhibit this most
elusive category of primary ferroic orders. We first define how ferrotoroidic order fits in with …

Symmetry analysis of current-induced switching of antiferromagnets

H Watanabe, Y Yanase - Physical Review B, 2018 - APS
Antiferromagnets are robust to external electric and magnetic fields, and hence are
seemingly uncontrollable. Recent studies, however, realized the electrical manipulations of …

Tuning magnetoelectricity in a mixed-anisotropy antiferromagnet

E Fogh, B Klemke, M Reehuis, P Bourges… - Nature …, 2023 - nature.com
Control of magnetization and electric polarization is attractive in relation to tailoring materials
for data storage and devices such as sensors or antennae. In magnetoelectric materials …

Magnetic structures and quadratic magnetoelectric effect in beyond 30 T

E Fogh, T Kihara, R Toft-Petersen, M Bartkowiak… - Physical Review B, 2020 - APS
Neutron diffraction with static and pulsed magnetic fields is used to directly probe the
magnetic structures in LiNiPO 4 up to 25 T and 42 T, respectively. By combining these …
