Gapless superconductivity from extremely dilute magnetic disorder in 2H-NbSe2-xSx

This study reveals that extremely dilute magnetic disorder induces gapless superconductivity in 2H-NbSe2-xSx, a phenomenon driven by Se-S substitution-induced band structure modifications that alter in-gap scattering mechanisms and challenge the conventional understanding of disorder robustness in superconductors.
