Enhancement of the Topological Hall Effect through Engineering the Skyrmion Size and Shape
Kazuma Murata, Ryunosuke Terasawa, Hiroaki Ishizuka
The topological Hall effect of skyrmions is a promising electrical probe of magnetic textures, but its small magnitude limits applications. In this work, we theoretically investiga…
Electrical control of spin photocurrent in a magnetoelectric oxide CrO
Zhuo-Cheng Gu, Hiroaki Ishizuka
Controlling magnetism by electric field or current is a central topic in spintronics. In this work, we argue that the magnon spin photocurrent can also be controlled by the electri…
Kondo Effect in Nonreciprocal Response
Hajime Murata, Hiroaki Ishizuka
Chiral magnetic states give rise to rich phenomena, from the anomalous Hall effect and the nonlinear electrical current to multiferroics and magnetochiral dichroism. Most of the st…
Controlling resonant spin photocurrent using magnetic field; application to a magnetoelectric oxide Cr2O3
Zhuo-Cheng Gu, Hiroaki Ishizuka
We study the magnon spin photocurrent in effective spin models for Cr2O3, a material known for its magnetoelectric effect. Using nonlinear response theory, we show that magnon spin…
Sign-reversal and non-monotonicity of chirality-related anomalous Hall effect in highly conductive metals
Ryunosuke Terasawa, Masafumi Udagawa, Hiroaki Ishizuka
The non-monotonic temperature dependence and sign reversal of chirality-related anomalous Hall effect in highly conductive metals are studied. Through the analysis of scattering ra…
Anomalous enhancement of large-momentum scattering by electron-electron interaction in moiré superlattices
Taiki Sato, Hiroaki Ishizuka
Using a microscopic model, we show that the electron-electron interaction of flat bands deviates significantly from the Coulomb interaction. In particular, we find that large-momen…
