Spin-charge conversion and current vortex in spin-orbit coupled systems
Junji Fujimoto, Florian Lange, Satoshi Ejima +4
Using response theory, we calculate the charge-current vortex generated by spin pumping at a point-like contact in a system with Rashba spin-orbit coupling. We discuss the spatial…
Generation of current vortex by spin current in Rashba systems
Florian Lange, Satoshi Ejima, Junji Fujimoto +4
Employing unbiased large-scale time-dependent density-matrix renormalization-group simulations, we demonstrate the generation of a charge-current vortex via spin injection in the R…
Theoretical Prediction of Two-Dimensional Functionalized MXene Nitrides as Topological Insulators
Yunye Liang, Mohammad Khazaei, Ahmad Ranjbar +5
Recently, two-dimensional (2D) transition metal carbides and nitrides, namely, MXenes have attracted lots of attention for electronic and energy storage applications. Due to a larg…
Spin-anisotropic magnetic impurity in a Fermi gas: poor man's scaling equation integration
Eugene Kogan, Kazuto Noda, Seiji Yunoki
We consider a single magnetic impurity described by the spin--anisotropic s-d(f) exchange (Kondo) model and formulate scaling equation for the spin-anisotropic model when the densi…
First-principles study of the spin-mixing conductance in Pt/NiFe junctions
Qinfang Zhang, Shin-ichi Hikino, Seiji Yunoki
Based on the spin-pumping theory and first-principles calculations, the spin-mixing conductance (SMC) is theoretically studied for Pt/Permalloy (NiFe, Py) junctions.…
