Spin-charge conversion in NiMnSb Heusler alloy films
Zhenchao Wen, Zhiyong Qiu, Sebastian Tolle +7
Half-metallic Heusler alloys are attracting considerable attention because of their unique half-metallic band structures which exhibit high spin polarization and yield huge magneto…
Spin colossal magnetoresistance in an antiferromagnetic insulator
Zhiyong Qiu, Dazhi Hou, Joseph Barker +3
Colossal magnetoresistance (CMR) refers to a large change in electrical conductivity induced by a magnetic field in the vicinity of a metal-insulator transition and has inspired ex…
Spin transport across antiferromagnets induced by the spin Seebeck effect
Joel Cramer, Ulrike Ritzmann, Bo-Wen Dong +5
For prospective spintronics devices based on the propagation of pure spin currents, antiferromagnets are an interesting class of materials that potentially entail a number of advan…
Antiferromagnetic anisotropy determination by spin Hall magnetoresistance
Hua Wang, Dazhi Hou, Zhiyong Qiu +3
An electric method for measuring magnetic anisotropy in antiferromagnetic insulators (AFIs) is proposed. When a metallic film with strong spin-orbit interactions, e.g., platinum (P…
Perpendicular magnetic anisotropy in insulating ferrimagnetic gadolinium iron garnet thin films
H. Maier-Flaig, S. Geprägs, Z. Qiu +5
We present experimental control of the magnetic anisotropy in a gadolinium iron garnet (GdIG) thin film from in-plane to perpendicular anisotropy by simply changing the sample temp…
Ferroic collinear multilayer magnon spin valve
Joel Cramer, Felix Fuhrmann, Ulrike Ritzmann +10
Information transport and processing by pure magnonic spin currents in insulators is a promising alternative to conventional charge-current driven spintronic devices. The absence o…
Detection of induced paramagnetic moments in Pt on YFeO via x-ray magnetic circular dichroism
Takashi Kikkawa, Motohiro Suzuki, Jun Okabayashi +4
Magnetic moments in an ultra-thin Pt film on a ferrimagnetic insulator YFeO (YIG) have been investigated at high magnetic fields and low temperatures by means of X-r…
Magnon Polarons in the Spin Seebeck Effect
Takashi Kikkawa, Ka Shen, Benedetta Flebus +5
Sharp structures in magnetic field-dependent spin Seebeck effect (SSE) voltages of Pt/YFeO (YIG) at low temperatures are attributed to the magnon-phonon interact…
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…
Plasmonic generation of spin currents
Ken-ichi Uchida, Hiroto Adachi, Daisuke Kikuchi +4
Surface plasmons, free-electron collective oscillations in metallic nanostructures, provide abundant routes to manipulate light-electron interactions that can localize light energy…
