Abstract: Using intrinsic multiple-Andreev-reflection-effect spectroscopy, we studied ballistic superconductor-normal metal-superconductor (SnS) contacts in layered oxypnictide superconductors NdFeAsO0.6H0.36 with critical temperatures Tc=45−48 K. We directly determined the magnitude of two bulk superconducting order parameters, the large gap… read more here.

DOI: 10.1103/physrevb.104.174512
Abstract: Using multiple Andreev reflection (MAR) spectroscopy, we studied superconductor normal metal superconductor (SnS) semiballistic contacts with incoherent transport in overdoped pnictide superconductors BaFe1.86Ni0.14As2 with critical temperature Tc ≈ 12 K. We directly determined an anisotropic… read more here.
