Temperature Dependence of Superconducting Gaps in Mg(Al)B2 System Investigated by SnS-Andreev Spectroscopy
S. A. Kuzmichev, T. E. Shanygina, S. N. Tchesnokov +1
Detailed temperature dependence of both superconducting gaps was obtained directly by means of SnS-Andreev spectroscopy. The Δσ,π(T) -curves were shown to be deviated from standard…
Crossed Andreev reflection and spin-resolved non-local electron transport
Mikhail S. Kalenkov, Andrei D. Zaikin
The phenomenon of crossed Andreev reflection (CAR) is known to play a key role in non-local electron transport across three-terminal normal-superconducting-normal (NSN) devices. He…
On the possible common nature of the ground state in Cu- and Fe-based HTSCs
K. V. Mitsen, O. M. Ivanenko
A qualitative model describing the ground state and the mechanism of superconducting pairing in Cu- and Fe-based high-temperature superconductors (HTSCs) is suggested. In this mode…
On the possible mechanism of superconductivity in cuprates and pnictides
K. V. Mitsen, O. M. Ivanenko
The nature of the normal state and the mechanism of superconductivity in two families of high-temperature superconductors, cuprates and pnictides, remain a matter of intense discus…
Triplet superconductivity in a ferromagnetic vortex
Mikhail S. Kalenkov, Andrei D. Zaikin, Victor T. Petrashov
We argue that odd-frequency triplet superconductivity can be conveniently realized in hybrid superconductor-ferromagnet (SF) structures with a ferromagnetic vortex. We demonstrate…
Observation of Multi-Gap Superconductivity in GdO(F)FeAs by Andreev Spectroscopy
T. E. Shanygina, Ya. G. Ponomarev, S. A. Kuzmichev +9
We have studied current-voltage characteristics of Andreev contacts in polycrystalline GdOFFeAs samples with bulk critical temperature = (52.5 \pm 1)K usi…
