Single-crystal neutron diffraction study was performed for anomalous antiferromagnetic ordering in a heavy-electron superconductor CeNiGe $_{3}$ . We observed incommensurate magnetic Bragg reflections characterized with the propagation vector of $k_{2}$ = (0; 0:41; 1=2) below the Nel temperature of 5 K, while there is no significant magnetic reflection at the commensurate propagation vector of $k_{1}$ = (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 $_{3}$ at ambient pressure is characterized only by the incommensurate propagation vector $k_{2}$ .

The materials, M $_{3}$ H(XO $_{4}$ ) $_{2}$ (M=alkaline metal, X=Se, S), exhibit high protonic conductivities in a relatively low temperature region. The high protonic conductivities emerge upon a structural phase transition and the phase transition temperature (Tc) varies depending on the elements of M and X. In this study, mixed materials, Rb $_{3-x}$ K $_{x}$ H(SeO $_{4}$ ) $_{2}$ , were studied by means of conductivity measurements and single crystal neutron structure analyses in order to clarify how the elements at the M site affect the Tc from the structural aspect. The conductivity measurements revealed that the Tc decreased as the K content increased. The variation of the Tc was found to be non-linear with respect to the K content. The structure analyses showed that the K ions preferred to occupy one of two M sites and the occupancy of the K ion at this site non-linearly varied. In addition, the SeO $_{4}$ tetrahedron became more distorted as the K content increased, suggesting the close relationship between the distortion and the Tc.
