Zero field (ZF) and transverse field (TF) muon spin relaxation and rotation (μSR) experiments have been carried out in the Cd-doped heavy fermion superconductor CeCoIn₅ to investigate its superconducting state. The ZF-μSR results in CeCo (In_0.97Cd_0.03)₅ revealed that no spontaneous magnetic field was induced below its superconducting transition temperature (T_c), indicating no evidence for time reversal symmetry breaking. The muon Knight shifts obtained from TF-μSR measurements decrease significantly below T_c, consistent with a spin-singlet state as in the parent compound CeCoIn₅, which is a d-wave superconductor.
