Table 1: θSH: spin Hall angle, δ: conductivity, δSH: spin Hall conductivity. The figures in the bottom row are those achieved in the present study. Remarkably, the spin Hall conductivity, shown in the right-hand column, is two orders of magnitude greater than the previous record. (Image: Pham Nam Hai)

BiSb expands the potential of topological insulators for ultra-low-power electronic devices. Scientists have developed the world’s best-performing pure spin current source made of bismuth-antimony (BiSb) alloys, which they report as the best candidate for the first industrial application of topological insulators...
