Direct observation of the spin exciton in Andreev spectroscopy of iron-based superconductors
M. M. Korshunov, S. A. Kuzmichev, T. E. Kuzmicheva
Quasiparticle excitations provide viable information on the physics of unconventional superconductors. Higgs and Leggett modes are some of the classic examples. Another important b…
Evolution of Superconducting Gaps in Th-Substituted SmThOFeAs Studied by Multiple Andreev Reflection Spectroscopy
T. E. Kuzmicheva, S. A. Kuzmichev, K. S. Pervakov +2
Using intrinsic multiple Andreev reflections effect (IMARE) spectroscopy, we studied SnS contacts in the layered oxypnictide superconductors SmThOFeAs with various thor…
Probing Bulk Superconducting Order Parameter in Ba(K)FeAs by Four Complementary Techniques
A. V. Muratov, T. E. Kuzmicheva, A. V. Sadakov +7
Using four different experimental techniques, we performed comprehensive studies of the bulk superconductive properties of single crystals of the nearly optimally doped $Ba_{1-x}K_…
Vortex Structure and Anisotropic Superconducting Gaps in Ba[Fe(Ni)]As
T. E. Kuzmicheva, V. A. Vlasenko, S. Yu. Gavrilkin +4
We studied nearly optimally Ni-substituted BaFeNiAs (BFNA) single crystals with \,K. In irreversible magnetization measurements, we determined the…
Lower critical field and SNS-Andreev spectroscopy of 122-arsenides: Evidence of nodeless superconducting gap
M. Abdel-Hafiez, P. J. Pereira, S. A. Kuzmichev +10
Using two experimental techniques, we studied single crystals of the 122-FeAs family with almost the same critical temperature, Tc. We investigated the temperature dependence of th…
Study of the Two-Gap Superconductivity in GdO(F)FeAs by ScS-Andreev Spectroscopy
T. E. Shanygina, Ya. G. Ponomarev, S. A. Kuzmichev +9
Current-voltage characteristics and dynamic conductance of the superconductor - constriction - superconductor junctions in GdO(F)FeAs polycrystalline samples with critical temperat…
