- Abstract
- The performance of spintronic devices critically depends on three material parameters, namely, the spin polarization in the current (P), the intrinsic Gilbert damping (alpha), and the coefficient of the nonadiabatic spin transfer torque (beta). However, there has been no method to determine these crucial material parameters in a self-contained manner. Here we show that P, alpha, and beta can be simultaneously determined by performing a single series of time-domain measurements of current-induced spin wave dynamics in a ferromagnetic film.
