An interest of spin-polarized electrons playing a central role in spintronics has been growing in optoelectronic applications using circularly polarized light. At an earlier stage in this field, an attention was paid to a spin-polarized electron emission from semiconductor heterostructures, e.g., by using a strained GaAs thin-layer that leads to exited electrons with highly spin-polarization as much as 86%. Although first-principles calculation is known to be an effective tool to search such materials, there is no report available. In the present work, the magneto-optical conductivity to spin currents for 5d heavy metals, as well as GaAs, were investigated in order to search the material candidates.
