Gate-Tunable Superconducting Spin Valve in a van der Waals Ferromagnet/Superconductor/Ferromagnet Trilayer
A. S. Ianovskaia, G. A. Bobkov, A. M. Bobkov +1
We theoretically demonstrate a gate-tunable superconducting spin valve effect (SVE) in a van der Waals (vdW) heterostructure composed of a monolayer superconductor (S) sandwiched b…
Anomalous phase shift and superconducting diode effect in Josephson junctions via thin films of rare-earth intermetallic magnets
G. A. Bobkov, I. A. Shvets, I. V. Bobkova +3
The superconductor/ferromagnet/superconductor (S/F/S) Josephson junctions (JJs) with an anomalous ground state phase shift (-S/F/S JJs) enable the implementa…
Theory of planar quasi-ballistic Josephson junctions
G. A. Bobkov, I. V. Bobkova, A. M. Bobkov +2
We develop a theoretical framework for planar quasi-ballistic Josephson junctions, where multiple superconducting leads are coupled through a large, nearly ballistic normal metal c…
Multiterminal Ballistic Josephson Effect in Monocrystalline Gold
K. B. Polevoy, G. A. Bobkov, D. S. Kalashnikov +6
We report on the realization of a planar, quasi-ballistic Josephson junction array using a Au micron-sized single-crystal. The system exhibits a nonlocal, multiterminal Josephson e…
Andreev bound states at nonmagnetic impurities in superconductor/antiferromagnet heterostructures
G. A. Bobkov, I. V. Bobkova, A. M. Bobkov
Andreev bound states can occur at single impurities in superconductors if the impurities suppress superconductivity for a given system. In particular, well-known Yu-Shiba-Rusinov s…
Néel proximity effect at antiferromagnet/superconductor interfaces
G. A. Bobkov, I. V. Bobkova, A. M. Bobkov +1
Spin-splitting induced in a conventional superconductor weakens superconductivity by destroying spin-singlet and creating spin-triplet Cooper pairs. We demonstrate theoretically th…
