Acoustoelectric non-local spin wave power detector for studying magnon-phonon coupling
Hiroki Matsumoto, Yasuhiro Todaka, Takuya Kawada +2
We have developed a simple detection scheme to study spin waves excited by surface acoustic wave (SAW) in ferromagnetic thin films. Metallic antennas made of Ta and a ferromagnetic…
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…
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…
Electric field modulation of the non-linear areal magnetic anisotropy energy
Yong-Chang Lau, Peng Sheng, Seiji Mitani +2
We study the ferromagnetic layer thickness dependence of the voltage-controlled magnetic anisotropy (VCMA) in gated CoFeB/MgO heterostructures with heavy metal underlayers. When th…
