Superconductivity in hole-doped germanium point contacts
N. V. Gamayunova, M. Kuzmiak, P. Szabo +2
We have observed superconductivity in heavy p-doped Ge by measuring of differential resistance dV/dI(V) of Ge - PtIr point contacts. The superconducting (SC) features disappear abo…
Sub-kelvin Andreev reflection spectroscopy of superconducting gaps in FeSe
D. L. Bashlakov, N. V. Gamayunova, L. V. Tyutrina +4
Point contact Andreev reflection studies have been conducted on FeSe single crystals by lowering the temperatures down to 0.5 K. The point contact Andreev reflection spectra were a…

N. V. Gamayunova, D. L. Bashlakov, O. E. Kvitnitskaya +4
Investigation of the electron-phonon interaction (EPI) in LaCuSb2 and La(Cu0.8Ag0.2)Sb2 compounds by Yanson point-contact spectroscopy (PCS) has been carried out. Point-contact spe…
The superconducting gaps in FeSe studied by soft point-contact Andreev reflection spectroscopy
Yu. G. Naidyuk, O. E. Kvitnitskaya, N. V. Gamayunova +6
FeSe single crystals have been studied by soft point-contact Andreev-reflection spectroscopy. Superconducting gap features in the differential resistance dV/dI(V) of point contacts…
Analysis of nonlinear conductivity of point contacts on the base of FeSe in the normal and superconducting state
Yu. G. Naidyuk, N. V. Gamayunova, O. E. Kvitnitskaya +3
Nonlinear conductivity of point contacts (PCs) on the base of FeSe single crystals has been investigated. Measured dV/dI dependencies demonstrate the prevailing contribution to the…
Analysis of point contact spectra of kfe2as2 in the thermal regime
N. V. Gamayunova, O. E. Kvitnitskaya, N. L. Bobrov +1
The point-contact spectra of the iron-based compound KFe2As2 were analyzed according to the thermal regime theory. We have obtained the values of the residual resistivity, the Lore…
