Spin diffusion and magnetoresistance in ferromagnet/topological-insulator junctions
Takehito Yokoyama, Yaroslav Tserkovnyak
We study spin and charge diffusion in metallic-ferromagnet/topological-insulator junctions. The coupled diffusion equations are derived perturbatively with respect to the strength…
Giant magnetoresistance in the junction of two ferromagnets on the surface of diffusive topological insulators
Katsuhisa Taguchi, Takehito Yokoyama, Yukio Tanaka
We reveal the giant magnetoresistance induced by the spin-polarized current in the ferromagnet (F_1)/topological insulator (TI)/ferromagnet (F_2) junction, where two ferromagnets a…
Superconducting Proximity Effect in Silicene: Spin-Valley Polarized Andreev Reflection, Non-Local Transport, and Supercurrent
Jacob Linder, Takehito Yokoyama
We theoretically study the superconducting proximity effect in silicene, which features massive Dirac fermions with a tunable mass (band gap), and compute the conductance across a…
Controllable valley and spin transports in ferromagnetic silicene junctions
Takehito Yokoyama
We investigate charge, valley, and spin transports in normal/ferromagnetic/normal silicene junc- tion. We show that the charge, valley, and spin conductances in this junction oscil…
Spintronics and spincaloritronics in topological insulators
Takehito Yokoyama, Shuichi Murakami
We study spintronics and spincaloritronics in topological insulators. We show spintronics effects in 2D topological insulator junctions and 3D topological insulators coupled to fer…
