Evidence for spin swapping from modulation of transverse resistance in magnetic heterostructures with Rashba interface
Heeman Kim, Shutaro Karube, Juan Borge +3
We investigate the transverse response under the out-of-plane magnetic field for magnetic heterostructures with Cu/Bi2O3 or Ag/Bi2O3 Rashba interfaces. We detect opposite contribut…
Néel vector rotation driven by spin-orbit torque in amorphous ferrimagnetic GdCo
Tetsuma Mandokoro, Yoichi Shiota, Tomoya Ito +5
Spin superfluidity, a phenomenon enabling low dissipative spin transport analogous to superfluidity in liquid helium and superconductivity in electronic systems, has remained a the…
Quantitative evaluation method for magnetoelastic coupling between surface acoustic waves and spin waves using electrical and optical measurements
Haruka Komiyama, Ryusuke Hisatomi, Kotaro Taga +6
Coupling and hybridization of different elementary excitations leads to new functionalities. In phononics and spintronics, magnetoelastic coupling between Rayleigh-type surface aco…
Handedness manipulation of propagating antiferromagnetic magnons
Yoichi Shiota, Tomohiro Taniguchi, Daiju Hayashi +5
Antiferromagnetic magnons possess a distinctive feature absent in their ferromagnetic counterparts: the presence of two distinct handedness modes, the right-handed (RH) and left-ha…
Observation of spin-splitter torque in collinear antiferromagnetic RuO
Shutaro Karube, Takahiro Tanaka, Daichi Sugawara +3
The spin-splitter effect is theoretically predicted to generate an unconventional spin current with - and - spin polarization via the spin-split band in ant…
Observation of unconventional spin polarization induced spin orbit torque in L1-ordered antiferromagnetic MnPt thin films
Longjie Yu, Shutaro Karube, Min Liu +3
Non-collinear antiferromagnets exhibits richer magneto-transport properties due to the topologically nontrivial spin structure they possess compared to conventional nonmagnetic mat…
Anomalous spin-orbit field via Rashba-Edelstein effect at W/Pt interface
Shutaro Karube, Nobuki Tezuka, Makoto Kohda +1
We have studied spin-orbit (SO) field in NiFe(Py)/W/Pt trilayer by means of spin-torque ferromagnetic resonance, and demonstrated that the W/Pt interface generates an…
Spin-current-related magnetoresistance in epitaxial Pt/Co bilayers in the presence of spin Hall effect and Rashba-Edelstein effect
Ye Du, Saburo Takahashi, Junsaku Nitta
We analyze the experimentally obtained spin-current-related magnetoresistance in epitaxial Pt/Co bilayers by using a drift-diffusion model that incorporates both bulk spin Hall eff…
Clear variation of spin splitting by changing electron distribution at non-magnetic metal/Bi2O3 interfaces
Hanshen Tsai, Shutaro Karube, Kouta Kondou +3
Large spin splitting at Rashba interface, giving rise to strong spin-momentum locking, is essential for efficient spin-to-charge conversion. Recently, a Cu/Bismuth oxide (Bi2O3) in…
Evaluation of bulk-interface contributions to Edelstein magnetoresistance at metal/oxide interfaces
Junyeon Kim, Yan-Ting Chen, Shutaro Karube +4
We report a systematic study on Edelstein magnetoresistance (Edelstein MR) in Co25Fe75/Cu/Bi2O3 heterostructures with a strong spin-orbit interaction at the Cu/Bi2O3 interface. We…
Experimental observation of spin to charge current conversion at non-magnetic metal/Bi2O3 interfaces
Shutaro Karube, Kouta Kondou, YoshiChika Otani
We here demonstrate the interfacial spin to charge current conversion by means of spin pumping from a ferromagnetic Permalloy (Py: Ni80Fe20) to a Cu/Bi2O3 interface. A clear signat…

Shutaro Karube, Hiroshi Idzuchi, Kouta Kondou +2
We have studied spin relaxation characteristics in a Ag nanowire covered with various oxide layers of Bi2O3, Al2O3, HfO2, MgO or AgOx by using non-local spin valve structures. The…
