TL;DR
This paper proposes that ferromagnetic vortex structures in superconductor-ferromagnet hybrids can host long-range triplet superconductivity, enabling measurable supercurrents due to proximity effects, thus offering a new platform for studying unconventional superconductivity.
Contribution
It introduces a novel mechanism for realizing odd-frequency triplet superconductivity in SF structures with ferromagnetic vortices, highlighting their potential for experimental detection.
Findings
Long-range triplet pairing can be induced in SF structures with ferromagnetic vortices.
Supercurrents in SFS junctions with vortices are appreciable and experimentally measurable.
The proposed setup provides a new platform for studying unconventional superconductivity.
Abstract
We argue that odd-frequency triplet superconductivity can be conveniently realized in hybrid superconductor-ferromagnet (SF) structures with a ferromagnetic vortex. We demonstrate that due to proximity-induced long-range triplet pairing such SFS junctions can sustain appreciable supercurrent which can be directly measured in experiments.
