Spin treacle in a frustrated magnet observed with spin current
Hiroki Taniguchi, Mori Watanabe, Takashi Ibe +8
By means of spin current, the flow of spin angular momentum, we find a regime of "spin treacle" in a frustrated magnetic system. To establish its existence, we have performed spin…
Negative resistance state in superconducting NbSe induced by surface acoustic waves
Masahiko Yokoi, Satoshi Fujiwara, Tomoya Kawamura +5
We report a negative resistance, namely, a voltage drop along the opposite direction of a current flow, in the superconducting gap of NbSe thin films under the irradiation of s…
Butterfly-shaped magnetoresistance in triangular-lattice antiferromagnet AgCrO
Hiroki Taniguchi, Mori Watanabe, Masashi Tokuda +8
Spintronic devices using antiferromagnets (AFMs) are promising candidates for future applications. Recently, many interesting physical properties have been reported with AFM-based…
Etching process of narrow wire and application to tunable-barrier electron pump
Shota Norimoto, Shuichi Iwakiri, Masahiko Yokoi +3
Single electron sources have been studied as a device to establish an electric current standard for 30 years and recently as an on-demand coherent source for Fermion quantum optics…
Field-induced SU(4) to SU(2) Kondo crossover in a half-filling nanotube dot: spectral and finite-temperature properties
Yoshimichi Teratani, Rui Sakano, Tokuro Hata +4
We study finite-temperature properties of the Kondo effect in a carbon nanotube (CNT) quantum dot using the Wilson numerical renormalization group (NRG). In the absence of magnetic…
