Josephson diode effect via a non-equilibrium Rashba system
Michiyasu Mori, Wataru Koshibae, Sadamichi Maekawa
A non-equilibrium state in a Rashba system under an in-plane magnetic field is identified as the origin of the Josephson diode effect. This state is induced by a current bias--nece…
Symmetry of the emergent inductance tensor exhibited by magnetic textures
Soju Furuta, Wataru Koshibae, Fumitaka Kagawa
Metals hosting gradually varying spatial magnetic textures are attracting attention as a new class of inductor. Under the application of an alternating current, the spin-transfer-t…
Electron Hydrodynamics by Spin Hall Effect
Junji Fujimoto, Wataru Koshibae, Sadamichi Maekawa
Electron hydrodynamics is currently known to emerge only when electron-electron interaction dominates over the momentum-nonconserving scatterings of electrons, where the electron t…
Direct visualization of three-dimensional shape of skyrmion strings in a noncentrosymmetric magnet
S. Seki, M. Suzuki, M. Ishibashi +6
Magnetic skyrmion, i.e. a topologically stable swirling spin texture, appears as a particle-like object in the two-dimensional (2D) systems, and has recently attracted attention as…
Bulk and surface topological indices for a skyrmion string
Wataru Koshibae, Naoto Nagaosa
The magnetic skyrmion is a topological magnetic vortex, and its topological nature is characterized by an index called skyrmion number which is a mapping of the magnetic moments de…
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…
