Abstract
The theory of size effects in the magnetoresistance of thin films of normal metals due to spin‑orbit interaction, which takes into account the surface scattering of conduction electrons with spin reversal, has been constructed. Experimental studies of structural and galvanomagnetic properties of β‑tantalum thin films of different thicknesses prepared by magnetron sputtering have been carried out. Based on the analysis of experimental data within the framework of the constructed theory, estimates of the spin diffusion length, spin relaxation time, and spin Hall angle for β‑tantalum thin films were made.
