We study the effect of nonmagnetic Zn impurity on superconductivity in the LaFe1−yZnyPO0.94F0.06 system by measuring the transport and magnetic properties. It is found that Zn doping drastically suppresses the superconducting transition temperature Tc. This is consistent with the theoretic prediction in the scenario of s±-wave or d-wave pairing.
