摘要：

The Co substitution effects on the superconductivity of FeSe0.4Te0.6 single crystals were investigated. The magnetic susceptibility measurement suggests that Co is non- magnetic in these materials. The superconducting transition temperature decreases linearly for Co doping with the rate -0.75 K/Co%, while the increasing rate of residual resistivity is less than 12.5 mu Omega.cm/Co%. Our data do not contradict the expectation for the s+/- pairing. (C) 2011 Published by Elsevier Ltd. Selection and/or peer-review under responsibility of ISS Program Committee.
