| Resumo: | Background incl. aims CuBi alloys are predicted to exhibit a giant spin Hall effect (SHE), making them promising materials for developing spintronic devices. This prediction was supported by the direct observation of SHE in Cu95Bi5 films by X-ray spectroscopy. However, the material composition and structure, e.g. crystallinity, crystallite size, effective Bi insertion into the Cu lattice or formation of metallic clusters of Bi, can affect the spin Hall angle, which is related to the efficiency of the spin-to-charge current conversion. This efficiency becomes more and more critical in the case of reduced dimensionality systems, where some dimensions may become smaller than the spin diffusion length. Changes taking place during device operation, such as those related to Joule heating, may also affect the system performance. |
