Strain-engineered long-distance supercurrent in an altermagnetic CrSb based-Josephson junction
Researchers demonstrated long-distance Josephson supercurrent transport through strained altermagnetic CrSb thin films, exceeding conventional limits by two orders of magnitude. This suggests the generation of long-distance spin-triplet Cooper pairs mediated by momentum-dependent spin splitting and strain-induced symmetry breaking, opening a new platform for superconducting spintronics.
