Calculating spin transport properties from first principles: Spin currents
Calculating spin transport properties from first principles: Spin currents
Experiments usually don't measure things favored by theorists like Green's functions or scattering matrices, rather, they measure chemical potentials and currents. Here, the authors have calculated local charge and spin currents in bulk platinum and permalloy from the results of relativistic first-principles quantum mechanical scattering calculations at finite temperatures.
