Almost half-quantized planar Hall effects in -wave magnets with
Motohiko Ezawa
The planar Hall effect is a phenomenon that the Hall conductivity emerges perpendicular to the electric field in the presence of an in-plane magnetic field. We investigate the plan…
Higher-order bulk photovoltaic effects, quantum geometry and application to -wave magnets
Motohiko Ezawa
The injection and shift currents are generalized to the th-order injection and shift currents for the longitudinal conductivities in the two-band model, where is the…
Quantum geometry and elliptic optical dichroism in -wave magnets
Motohiko Ezawa
The quantum geometric tensor is composed of the Berry curvature and the quantum metric, which is observable by means of optical absorption of elliptically polarized light. Especial…
Metallic -wave magnet with commensurate spin helix
Rinsuke Yamada, Max T. Birch, Priya R. Baral +20
Antiferromagnetic states with spin-split electronic structure give rise to novel spintronic, magnonic, and electronic phenomena despite (near-) zero net magnetization. The simplest…
Out-of-plane Edelstein effects: Electric-field induced magnetization in -wave magnets
Motohiko Ezawa
In-plane magnetization is induced by the Edelstein effect in the Rashba spin-orbit interaction system. However, out-of-plane magnetization is more useful for switching a ferromagne…
