Leggett's plasma resonances and two-gap structures in the CVCs of MgB $_{2}$ break junctions $-$ a direct evidence for a two-gap superconductivity in MgB $_{2}$

Ya. G. Ponomarev, S. A. Kuzmichev, M. G. Mikheev +13

In the present investigation (2002) the current-voltage characteristics (CVCs) of break junctions in polycrystalline $M g B_{2}$ samples have been studied in the temperature range $4.2…

Andreev spectroscopy of iron-based superconductors: temperature dependence of the order parameters and scaling of the $Δ_{L, S}$ with $T_{C}$

T. E. Kuzmicheva, S. A. Kuzmichev, M. G. Mikheev +5

We studied iron-based superconductors of various families with critical temperatures covering almost all range $T_{C} = 9 - 53$ K. In natural arrays of contacts formed in these mater…

Estimation of intraband and interband relative coupling constants from temperature dependences of the order parameter for two-gap superconductors

S. A. Kuzmichev, T. E. Kuzmicheva, S. N. Tchesnokov +2

We present temperature dependences of the large and the small superconducting gaps measured directly by SnS-Andreev spectroscopy in various Fe-based superconductors and MgB $_{2}$ . Th…

Intrinsic Multiple Andreev Reflections in layered Th-doped Sm $_{1 - x}$ Th $_{x}$ OFeAs

T. E. Kuzmicheva, S. A. Kuzmichev, S. N. Tchesnokov +1

Layered oxypnictide Sm $_{1 - x}$ Th $_{x}$ OFeAs (Sm-1111) is an ideal candidate to be probed by intrinsic multiple Andreev reflections effect (IMARE) spectroscopy. Using the classical "b…
