Chiral orbital texture in nonlinear electrical conduction
Suguru Okumura, Ryutaro Tanaka, Daichi Hirobe
Nonlinear electrical conduction primarily mediated by an orbital texture is observed in chiral semiconductor Te. We determine the enantiospecific sign of the nonlinear conductance…
Chirality-induced intrinsic charge rectification in a tellurium-based field-effect transistor
Daichi Hirobe, Yoji Nabei, Hiroshi M. Yamamoto
We report gate-induced enhancement of intrinsic charge rectification without p-n junctions in chiral semiconductor Te under magnetic field B. As gating shifts the chemical potentia…
Magnon Pairs and Spin-Nematic Correlation in the Spin-Seebeck Effect
Daichi Hirobe, Masahiro Sato, Masato Hagihala +3
Investigating exotic magnetic materials with spintronic techniques is effective at advancing magnetism as well as spintronics. In this work, we report unusual field-induced suppres…
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…
Magnetic thermal conductivity far above the Néel temperatures in the Kitaev-magnet candidate -RuCl
Daichi Hirobe, Masahiro Sato, Yuki Shiomi +2
We have investigated the longitudinal thermal conductivity of -RuCl, the magnetic state of which is considered to be proximate to a Kitaev honeycomb model, along with the…
Observation of spin current in quantum spin liquid
Daichi Hirobe, Masahiro Sato, Takayuki Kawamata +6
Spin liquid is a state of electron spins in which quantum fluctuation breaks magnetic ordering while maintaining spin correlation. It has been a central topic in magnetism because…
Generation of Spin Currents in the Skyrmion Phase of a Helimagnetic Insulator
Daichi Hirobe, Yuki Shiomi, Yuhki Shimada +2
We report spin-current generation related with skyrmion dynamics resonantly excited by a microwave in a helimagnetic insulator . A Pt layer was fabricated on $…
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…
