Times Cited Count：4 Percentile：34.89(Physics, Multidisciplinary)Single-crystal neutron diffraction study was performed for anomalous antiferromagnetic ordering in a heavy-electron superconductor CeNiGe. We observed incommensurate magnetic Bragg reflections characterized with the propagation vector of 
= (0; 0:41; 1=2) below the N
el temperature of 5 K, while there is no significant magnetic reflection at the commensurate propagation vector of 
= (1; 0; 0) at which another magnetic reflection was observed in the previous neutron diffraction study with a polycrystalline sample. From the single crystal study, we suggest that the magnetic phase of CeNiGe at ambient pressure is characterized only by the incommensurate propagation vector .
