Researchers in Japan using the Rashba effect for generating spin currents in material structures that possess electrons with desirable spin properties. They developed a mechanism to generate a spin current without energy loss from a series of simulations for new quasi-1D materials based on bismuth-adsorbed indium that exhibit a giant Rashba effect. This mechanism does not require an external magnetic field to generate nondissipative spin current. The process would simplify potential spintronic devices and would allow for further miniaturization… read more. Open Access TECHNICAL ARTICLE
a) Atomic structure of the H1-like undistorted structure. Spin-polarization components parallel to the (b) y axis and (c) z axis as open circles of the structure with the band dispersion. The radius of each circle is proportional to the magnitude of the spin component. Credit: http://dx.doi.org/10.1103/PhysRevB.98.241409
