Abstract

We study the relationship between the damping (alpha) and the nonadiabaticity of the spin transport (beta) in permalloy nanowires. alpha is engineered by Ho doping, and from the characteristics of the current-induced domain-wall velocity, determined by high-resolution x-ray magnetic circular-dichroism photoemission electron microscopy, beta due to spin relaxation is measured. We ...
