Robust Nodal Superconductivity Induced by Isovalent Doping in Ba(Fe_{1-x}Ru_{x})_{2}As_{2} and BaFe_{2}(As_{1-x}P_{x})_{2}

Robust Nodal Superconductivity Induced by Isovalent Doping in Ba(Fe_{1-x}Ru_{x})_{2}As_{2} and BaFe_{2}(As_{1-x}P_{x})_{2}

We present the ultra-low-temperature heat-transport study of iron-based superconductors Ba(Fe_{1-x}Ru_{x})_{2}As_{2} and BaFe_{2}(As_{1-x}P_{x})_{2}. For optimally doped Ba(Fe_{0.64}Ru_{0.36})_{2}As_{2}, a large residual κ_{0}/T at zero field and a sqrt[H] dependence of κ_{0}(H)/T are observed, whic...
