Itinerant Nature of U 5f States in Uranium Mononitride UN Revealed by Angle Resolved Photoelectron Spectroscopy
Shin-ichi Fujimori, Takuo Ohkochi, Tetsuo Okane +6
The electronic structure of the antiferromagnet uranium nitride (UN) has been studied by angle resolved photoelectron spectroscopy using soft X-rays (hn=420-520 eV). Strongly dispe…
High-field moment polarization in the ferromagnetic superconductor UCoGe
W. Knafo, T. D. Matsuda, D. Aoki +7
We report magnetization and magnetoresistivity measurements on the isostructural ferromagnetic superconductors UCoGe and URhGe in magnetic fields up to 60 T and temperatures from 1…
Longitudinal Spin Seebeck Effect Free from the Proximity Nernst Effect
T. Kikkawa, K. Uchida, Y. Shiomi +6
This letter provides evidence for intrinsic longitudinal spin Seebeck effects (LSSEs) that are free from the anomalous Nernst effect (ANE) caused by an extrinsic proximity effect.…
Spin Seebeck effect in antiferromagnets and compensated ferrimagnets
Yuichi Ohnuma, Hiroto Adachi, Eiji Saitoh +1
We theoretically investigate the spin Seebeck effect (SSE) in antiferromagnets and ferrimagnets, and show that the SSE vanishes in antiferromagnets but survives in ferrimagnets eve…
The spin Hall effect as a probe of nonlinear spin fluctuations
D. H. Wei, Y. Niimi, B. Gu +3
The spin Hall effect and its inverse play key roles in spintronic devices since they allow conversion of charge currents to and from spin currents. The conversion efficiency strong…
Cyclotron Resonance in the Hidden-Order Phase of URu2Si2
S. Tonegawa, K. Hashimoto, K. Ikada +9
We report the first observation of cyclotron resonance in the hidden-order phase of ultra-clean URuSi crystals, which allows the full determination of angle-dependent elect…
