Abstract

The effect of Co doping on the supercoductivity of FeSe 0.4Te 0.6 single crystals is investigated. The superconducting transition temperature decreases linearly for Co doping at a rate of -0.75K/(Co%). On the other hand, the increase in residual resistivity is less than 50μΩ cm for 4% Co doping. These data are consistent with the interband scattering mechanism of superconductivity with the sign change (s± symmetry).
