Circular dichroism in second- and third-harmonic generation in chiral topological semimetal CoSi
Yuya Ominato, Masahito Mochizuki
We theoretically investigate circular dichroism (CD) in second- and third-harmonic generation (SHG and THG) in the chiral topological semimetal CoSi. We demonstrate that both SHG a…
Nanofluidic logic based on chiral skyrmion flows
Xichao Zhang, Jing Xia, Yan Zhou +4
Particle-like chiral magnetic skyrmions can flow in nanotracks and behave like chiral fluids. Using interacting flows to perform logical operations is an important topic in microfl…
Switching magnetic texture via in-plane magnetic field in noncentrosymmetric dipolar magnets: From skyrmions to antiskyrmions and nontopological magnetic bubbles
Tatsuki Muto, Masahito Mochizuki
We theoretically investigate field-induced switching of magnetic topology in a nanodisk-shaped sample of noncentrosymmetric dipolar magnet in which the Dzyaloshinskii-Moriya intera…
Proposed controlled creation and manipulation of skyrmions with spin-orbit torque
Yuto Uwabo, Ryo Fujimoto, Kimimaro Yanai +1
The physical mechanisms underlying current-driven skyrmion motion include the spin-transfer torque exerted by a spin-polarized horizontal electric current and the spin-orbit torque…
Theoretical perspectives on optical control of magnetism in spin-charge coupled systems
Masahito Mochizuki
In this article, we review recent theoretical research on photocontrol of magnetism in several spin-charge coupled systems. The control of magnetism with light has been a central i…
Theoretically proposed controlled creation of Bloch-type skyrmions with spin-orbit torque in a chiral-ferromagnet/heavy-metal heterojunction
Yuto Uwabo, Masahito Mochizuki
The creation and manipulation of magnetic skyrmions in magnetic bilayer heterostructures via spin-orbit torque have been intensively studied in spintronics because of their potenti…
