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…
Josephson effect due to the long-range odd-frequency triplet superconductivity in SFS junctions with Neel domain walls
Ya. V. Fominov, A. F. Volkov, K. B. Efetov
We consider a SFS Josephson junction made of two superconductors S and a multidomain ferromagnet F with an in-plane magnetization. We assume that the neighboring domains of the fer…
Dephasing of conduction electrons by magnetic impurities in Cu/Ni and Cu/Cr samples: Influence of spin-glass transition on the superconducting proximity effect
I. Sosnin, P. Nugent, J. Zou +2
The dependence of the superconducting proximity effect on the amount of magnetic impurities in the normal part of Andreev interferometers has been studied experimentally. The depha…
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…
Odd triplet superconductivity in a superconductor/ferromagnet structure with a spiral magnetic structure
A. F. Volkov, A. Anishchanka, K. B Efetov
We analyze a superconductor-ferromagnet (S/F) system with a spiral magnetic structure in the ferromagnet F for a weak and strong exchange field. The long-range triplet component (L…
Oscillations of Induced Magnetization in Superconductor-Ferromagnet Heterostructures
M. Yu. Kharitonov, A. F. Volkov, K. B. Efetov
We study a change in the spin magnetization of a superconductor-ferromagnet (SF) heterostructure, when temperature is lowered below the superconducting transition temperature. It i…
