Spin-signal propagation in time-dependent noncollinear spin transport

Using a macroscopic analysis, we show that time-dependent noncollinear spin transport possesses a wavelike character. This leads to modifications of pure spin-diffusion dynamics and allows one to extract a finite spin-signal propagation velocity. We numerically study the dynamics of a pure spin current pumped into a nonmagnetic layer for precession frequencies ranging from GHz to THz.

Signal propagation in time-dependent spin transport

This paper analyzes theoretically the signal propagation in spin transport by modulating the current passing through magnetic multilayers. Using a macroscopic description of spin transport based on the dynamical Boltzmann equation, we show that time-dependent spin transport possesses a wave-like character that leads to modifications of pure spin-diffusion dynamics. In particular, the wave-like characteristics allow one to extract a finite spin signal-propagation velocity.
