Curvature-induced long-range supercurrents in diffusive superconductor-ferromagnet-superconductor Josephson junctions with a dynamic 0−π transition

We report that spin supercurrents can be induced in diffusive superconductor-ferromagnet-superconductor Josephson junctions without any magnetic misalignment or intrinsic spin-orbit coupling. Instead, the pathway to spin-triplet generation is provided via geometric curvature, and results a long-range effect. In addition, curvature shown induce dynamically tunable $0\text{\ensuremath{-}}\ensuremath{\pi}$ transition junction. provide analytic framework discuss potential experimental innovation implications.
