Spin-triplet supercurrents in superconductor / ferromagnet heterostructures

cimmel tart eloadast.


In a Josephson junction, the non-superconducting weak link connecting the two superconductors can sustain a finite supercurrent via spin-singlet Cooper pairs penetrating the non-superconducting material. However, if the weak link consists of a ferromagnetic material, this supercurrent decays in only a few nanometers because the presence of magnetism is disruptive for spin-singlet Cooper pairs. In our research, we investigated - both theoretically and experimentally - the possibility of generating a longer-ranged supercurrent through a magnetic material by converting the magnetically sensitive spin-singlet Cooper pairs into spin-triplet Cooper pairs that are robust against magnetism. This conversion is possible for example by introducing non-collinear magnets, helical magnets, or magnetic domain walls into the weak link.

Welcome - about us

Welcome! Nanopaprika was cooked up by Hungarian chemistry PhD student in 2007. The main idea was to create something more personal than the other nano networks already on the Internet. Community is open to everyone from post-doctorial researchers and professors to students everywhere.

There is only one important assumption: you have to be interested in nano!

Nanopaprika is always looking for new partners, if you have any idea, contact me at
