Scattering by magnetic and spin-orbit impurities and the Josephson current in superconductor-ferromagnet-superconductor junctions
F. S. Bergeret, A. F. Volkov, K. B. Efetov
We analyze the Josephson current in a junction consisting of two superconductors (S) and a ferromagnetic layer (F) for arbitrary impurity concentration. In addition to non-magnetic…
Reversing non-local transport through a superconductor by electromagnetic excitations
A. Levy Yeyati, F. S. Bergeret, A. Martin-Rodero +1
Superconductors connected to normal metallic electrodes at the nanoscale provide a potential source of non-locally entangled electron pairs. Such states would arise from Cooper pai…
Comment on ''Superconducting decay length in a ferromagnetic metal''
A. F. Volkov, F. S. Bergeret, K. B. Efetov
In the paper " Superconducting decay length in a ferromagnetic metal" by Gusakova, Kupriyanov and Golubov [Pis'ma v ZhETF 83, 487 (2006); cond-mat/0605137], the authors claim that…
Interplay between Josephson effect and magnetic interactions in double quantum dots
F. S. Bergeret, A. Levy Yeyati, A. Martin-Rodero
We analyze the magnetic and transport properties of a double quantum dot coupled to superconducting leads. In addition to the possible phase transition to a state, already pres…
