Comment on "Reconsidering the nonlinear emergent inductance: time-varying Joule heating and its impact on the AC electrical response"
Tomoyuki Yokouchi, Aki Kitaori, Daiki Yamaguchi +4
When non-collinear spin textures are driven by current, an emergent electric field arises due to the emergent electromagnetic induction. So far, this phenomenon has been reported i…
Emergent electric field induced by current-driven domain wall motion in a room-temperature antiferromagnet FeSn2
Tomoyuki Yokouchi, Yuta Yamane, Yasufumi Araki +2
Antiferromagnets have attracted extensive interest as platforms for nanoscale spintronic devices owing to ultrafast spin dynamics and lack of a stray field. One of the crucial miss…
Signature of BKT-like spin transport in a quasi-2D antiferromagnet BaNiVO
Kurea Nakagawa, Minoru Kanega, Tomoyuki Yokouchi +2
In two-dimensional (2D) spin systems, the augmentation of spin fluctuations gives rise to quasi-long-range order; however, how they manifest in spin transport remains unclear. Here…
Giant Magnetochiral Anisotropy in Weyl-semimetal WTe2 Induced by Diverging Berry Curvature
Tomoyuki Yokouchi, Yuya Ikeda, Takahiro Morimoto +1
The concept of Berry curvature is essential for various transport phenomena. However, an effect of the Berry curvature on magnetochiral anisotropy, i.e. nonreciprocal magneto-trans…
Pattern recognition with neuromorphic computing using magnetic-field induced dynamics of skyrmions
Tomoyuki Yokouchi, Satoshi Sugimoto, Bivas Rana +5
Nonlinear phenomena in physical systems can be used for brain-inspired computing with low energy consumption. Response from the dynamics of a topological spin structure called skyr…
Enhanced Electrical Magnetochiral Effect by Spin-hedgehog Lattice Structural Transition
Aki Kitaori, Naoya Kanazawa, Hiroaki Ishizuka +3
Nonreciprocal resistance, depending on both directions of current () and magnetic-field () or magnetization (), is generally expected to emerge in a chiral conductor, and…
Emergent electromagnetic induction beyond room temperature
Aki Kitaori, Naoya Kanazawa, Tomoyuki Yokouchi +3
Emergent electromagnetic induction based on electrodynamics of noncollinear spin states may enable dramatic miniaturization of inductor elements widely used in electric circuits, y…
Slow steady flow of a skyrmion lattice in a confined geometry probed by resistance narrow-band noise
Takuro Sato, Wataru Koshibae, Akiko Kikkawa +6
Using resistance fluctuation spectroscopy, we observe current-induced narrow-band noise (NBN) in the magnetic skyrmion-lattice phase of micrometer-sized MnSi. The NBN appears only…
Formation of In-plane Skyrmions in Epitaxial MnSi Thin Films as Revealed by Planar Hall Effect
T. Yokouchi, N. Kanazawa, A. Tsukazaki +7
We investigate skyrmion formation in both a single crystalline bulk and epitaxial thin films of MnSi by measurements of planar Hall effect. A prominent stepwise field profile of pl…
