Zero-field superconducting diode effect induced by magnetic flux in a van der Waals superconductor trigonal PtBi
Nan Jiang, Masaki Maeda, Yuhi Yamaguchi +9
The superconducting diode effect is one of the nonreciprocal transport phenomena, where the critical current depends on the current direction. This effect is typically realized in…
Observation of the crossover from quantum fluxoid to half-quantum fluxoid in a chiral superconducting device
Masashi Tokuda, Fumiya Matsumoto, Noriaki Maeda +16
Topological superconductors are one of the intriguing material groups from the viewpoint of not only condensed matter physics but also industrial application such as quantum comput…
Higher harmonic resistance oscillations in micro-bridge superconducting Nb ring
Masashi Tokuda, Ryoya Nakamura, Masaki Maeda +1
We studied resistance oscillations in two types of superconducting mesoscopic Nb rings. In a simple superconducting ring device, a resistance oscillation with a period of the quant…
Kondo effect in Lieb's ferrimagnetic system on the T-shaped bipartite lattice
Masashi Tokuda, Yunori Nishikawa
The minimal ferrimagnetism by Lieb's theorem emerges on the T-shaped bipartite lattice composed of four sites, which can be realized experimentally, just as Nagaoka ferromagnetism…
Thickness-induced crossover from strong to weak collective pinning in exfoliated FeTeSe thin films at 1 T
Ryoya Nakamura, Masashi Tokuda, Mori Watanabe +3
We studied flux pinning in exfoliated FeTeSe thin-film devices with a thickness from 30 to 150 nm by measuring the critical current density . In…
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…
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…
Quantum oscillations with magnetic hysteresis observed in CeTe thin films
Mori Watanabe, Sanghyun Lee, Takuya Asano +7
We have performed magnetotransport measurements in CeTe thin films down to . It is known that CeTe has two magnetic transitions at $T_{\rm N1} \approx 3~{\…
