Giant Magnetochiral Anisotropy in Weyl-semimetal WTe2 Induced by Diverging Berry Curvature
Tomoyuki Yokouchi, Yuya Ikeda, Takahiro Morimoto +1
The concept of Berry curvature is essential for various transport phenomena. However, an effect of the Berry curvature on magnetochiral anisotropy, i.e. nonreciprocal magneto-trans…
Triplon current generation in solids
Yao Chen, Masahiro Sato, Yifei Tang +6
A triplon refers to a fictitious particle that carries angular momentum corresponding to the elementary excitation in a broad class of quantum dimerized spin systems. Such…
Observation of nuclear-spin Seebeck effect
T. Kikkawa, D. Reitz, H. Ito +10
Thermoelectric effects have been applied to power generators and temperature sensors that convert waste heat into electricity. The effects, however, have been limited to electrons…
Modulation of Dirac electrons in epitaxial Bi2Se3 ultrathin films on van-der-Waals ferromagnet Cr2Si2Te6
Takemi Kato, Katsuaki Sugawara, Naohiro Ito +7
We investigated the Dirac-cone state and its modulation when an ultrathin film of topological insulator Bi2Se3 was epitaxially grown on a van-der-Waals ferromagnet Cr2Si2Te6 (CST)…
Spin Seebeck effect in the layered ferromagnetic insulators CrSiTe and CrGeTe
Naohiro Ito, Takashi Kikkawa, Joseph Barker +3
We have studied the longitudinal spin Seebeck effect (LSSE) in the layered ferromagnetic insulators CrSiTe and CrGeTe covered by Pt films in the measurement configuration w…
Observation of Magnetopiezoelectric Effect in Antiferromagnetic Metal EuMnBi2
Y. Shiomi, H. Watanabe, H. Masuda +3
We have experimentally studied a magnetopiezoelectric effect predicted recently for magnetic metals with low crystal symmetries. In EuMnBi2 with antiferromagnetic Mn moments at 77…
Spin Seebeck effect in a polar antiferromagnet -CuVO
Y. Shiomi, R. Takashima, D. Okuyama +5
We have studied the longitudinal spin Seebeck effect in a polar antiferromagnet -CuVO in contact with a Pt film. Below the antiferromagnetic transition tempera…
Universal scaling for the spin-electricity conversion on surface states of topological insulators
K. T. Yamamoto, Y. Shiomi, Kouji Segawa +2
We have investigated spin-electricity conversion on surface states of bulk-insulating topological insulator (TI) materials using a spin pumping technique. The sample structure is N…
Critical suppression of spin Seebeck effect by magnetic fields
Takashi Kikkawa, Ken-ichi Uchida, Shunsuke Daimon +3
The longitudinal spin Seebeck effect (LSSE) in Pt/YFeO (YIG) junction systems has been investigated at various magnetic fields and temperatures. We found that the LS…
Enhancement of Spin Pumping in Trilayer Film
Daichi Hirobe, Ryo Iguchi, Kazuya Ando +2
We study spin pumping in a trilayer film by means of the inverse spin Hall effect (ISHE). When the ferromagnets are not excited…
Bulk topological insulators as inborn spintronics detectors
Y. Shiomi, K. Nomura, Y. Kajiwara +5
Detection and manipulation of electrons' spins are key prerequisites for spin-based electronics or spintronics. This is usually achieved by contacting ferromagnets with metals or s…
Observation of the Magnon Hall Effect
Y. Onose, T. Ideue, H. Katsura +3
The Hall effect usually occurs when the Lorentz force acts on a charge current in a conductor in the presence of perpendicular magnetic field. On the other hand, neutral quasi-part…
