Nonreciprocal spin Seebeck effect in antiferromagnets
Rina Takashima, Yuki Shiomi, Yukitoshi Motome
We theoretically propose a nonreciprocal spin Seebeck effect, i.e., nonreciprocal spin transport generated by a temperature gradient, in antiferromagnetic insulators with broken in…
Generation and control of noncollinear magnetism by supercurrent
Rina Takashima, Yasuyuki Kato, Youichi Yanase +1
When superconductivity couples with noncollinear spin textures, rich physics arises; for instance, singlet Cooper pairs can be converted to triplet pairs, and topological supercond…
Spin Seebeck effect in a polar antiferromagnet -CuVO
Y. Shiomi, R. Takashima, D. Okuyama +5
We have studied the longitudinal spin Seebeck effect in a polar antiferromagnet -CuVO in contact with a Pt film. Below the antiferromagnetic transition tempera…
Signature of magnon Nernst effect in an antiferromagnetic insulator
Y. Shiomi, R. Takashima, E. Saitoh
A magnon Nernst effect, an antiferromagnetic analogue of the magnon Hall effect in ferromagnetic insulators, has been studied experimentally for a layered antiferromagnetic insulat…
Adiabatic and nonadiabatic spin torques induced by spin-triplet supercurrent
Rina Takashima, Satoshi Fujimoto, Takehito Yokoyama
We study spin transfer torques induced by a spin-triplet supercurrent in a magnet with the superconducting proximity effect. By a perturbative approach, we show that spin-triplet c…
Supercurrent-induced Skyrmion dynamics and Tunable Weyl points in Chiral Magnet with Superconductivity
Rina Takashima, Satoshi Fujimoto
Recent studies show superconductivity provides new perspectives on spintronics. We study a heterostructure composed of an s-wave superconductor and a cubic chiral-magnet that can s…
Quantum Skyrmions in Two-Dimensional Chiral Magnets
Rina Takashima, Hiroaki Ishizuka, Leon Balents
We study the quantum mechanics of magnetic skyrmions in the vicinity of the skyrmion-crystal to ferromagnet phase boundary in two-dimensional magnets. We show that the skyrmion exc…
Electrodynamics in Skyrmions Merging
Rina Takashima, Satoshi Fujimoto
In a recent study the coalescence of magnetic skyrmions was observed in a metallic chiral magnet Fe0.5Co0.5Si when the skyrmion phase is destroyed, and numerical simulations demons…
