Abstract

Read online

When entering a ferromagnet, a spin-singlet supercurrent decays rapidly, while a spin-triplet supercurrent can extend over much longer distances. Here, the authors observe long-range, spin triplet supercurrent in lateral Josephson junctions constructed using the van der Waals metallic ferromagnet Fe3GeTe2 as the weak link.
