Abstract: We study the structure of the superconducting order parameter in underdoped NaFe1x1xCoxxAs pnictides with Tc1921Tc1921 K related to the 111 family. Using incoherent multiple Andreev reflection effect spectroscopy of planar break junctions, we directly determine the magnitudes of the two microscopic superconducting order parameters: the small superconducting gap ΔS(0)ΔS(0), and possible edges of the large gap ΔL(0)ΔL(0) having an anisotropy in the abab plane at TTcTTc, the corresponding characteristic ratios, as well as their temperature dependences. Additionally, we detect features of the tunneling dI(V)/dVdI(V)/dV spectra in NaFe1x1xCoxxAs at eV>2ΔL(0)eV>2ΔL(0), those irrelative to superconducting state, and discuss their origin.
