Andreev reflection spectra have been measured in a new superconductor EuAsFeO₀.₈₅F₀.₁₅ having an unexpectedly low superconducting transition temperature Tc≈11.3 K among related FeAs compounds on a base Sm and Gd surrounding Eu in the series of lanthanides. The nearly fivefold lower Tc, as against th...
