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…
Modulation of Spin Seebeck Effect by Hydrogenation
K. Ogata, T. Kikkawa, E. Saitoh +1
We demonstrate the modulation of spin Seebeck effect (SSE) by hydrogenation in Pd/YIG bilayers. In the presence of 3% hydrogen gas, SSE voltage decreases by more than 50% from the…
