Extrinsic nonlinear spin currents in spin-orbit coupled systems: A Boltzmann transport study

We develop a semiclassical Boltzmann framework for second-order extrinsic spin transport in the presence of skew scattering. The conventional relaxation-time approximation reduces the full collision integral to a single phenomenological timescale and thereby neglects the angular structure of impurity scattering. While...
