- Abstract
- The Andreev reflection spectra sNS (V,T) = dI/dV (V,T) of Ag/FeSe point contacts were measured in the temperature range T = 4 – 14 K. Analysis of the spectra within the framework of a two-band model with order parameters of s-symmetry revealed two energy gaps Di (i = 1, 2) and allowed us to plot their dependences on temperature. Approximation of the Di(T ) dependencies by a two-band isotropic model in the “pure” limit showed that their description requires taking into account both intraband and interband interactions of superconducting condensates. Such a description corresponds to s- or s++-symmetry of the order parameter.
