On-chip all-electrical determination of the magnetoelastic coupling constant of magnetic heterostructures
Takuya Kawada, Isamu Yasuda, Masashi Kawaguchi +1
We have developed an approach to determine the magnetoelastic coupling constant of magnetic layers in thin film heterostructures. The film is formed on a piezoelectric substrate be…
Helicity resolved Raman spectroscopy of mono- and a few-layers thick PtSe
Isamu Yasuda, Takuya Kawada, Hiroki Matsumoto +2
We studied helicity resolved Raman scattering in PtSe flakes with different thicknesses. The peak amplitude of helicity-switched Raman scattering is significantly larger than t…
Anisotropy of the spin Hall effect in a Dirac ferromagnet
Guanxiong Qu, Masamitsu Hayashi, Masao Ogata +1
We study the intrinsic spin Hall effect of a Dirac Hamiltonian system with ferromagnetic exchange coupling, a minimal model combining relativistic spin-orbit interaction and ferrom…
Cavity magnomechanical coupling with coupled magnon modes in a synthetic antiferromagnet
Motoki Asano, Hiroki Matsumoto, Masamitsu Hayashi +1
On-chip cavity magnomechanics is an emerging field exploring acoustic and magnonic functionalities of various ferromagnetic materials and structures using strongly confined phonons…
Anomalous Hall effect of light-driven three-dimensional Dirac electrons in bismuth
Yoshua Hirai, Naotaka Yoshikawa, Masashi Kawaguchi +4
Recent advancement in laser technology has opened the path toward the manipulation of functionalities in quantum materials by intense coherent light. Here, we study three-dimension…
Spin Hall effect driven by the spin magnetic moment current in Dirac materials
Zhendong Chi, Guanxiong Qu, Yong-Chang Lau +5
The spin Hall effect of a Dirac Hamiltonian system is studied using semiclassical analyses and the Kubo formula. In this system, the spin Hall conductivity is dependent on the defi…
