Single magnetic adsorbates on s-wave superconductors

BW Heinrich, JI Pascual, KJ Franke - Progress in Surface Science, 2018 - Elsevier
In superconductors, magnetic impurities induce a pair-breaking potential for Cooper pairs,
which locally affects the Bogoliubov quasiparticles and gives rise to Yu-Shiba-Rusinov (YSR …

Hybrid helical state and superconducting diode effect in superconductor/ferromagnet/topological insulator heterostructures

T Karabassov, IV Bobkova, AA Golubov, AS Vasenko - Physical Review B, 2022 - APS
