用磁强计和中子衍射法研究了正交晶系CeRhGe和NdRhGe(TiNiSi型晶体结构)的磁性和结构性质。这两个标题化合物分别在10K和14K以下按反铁磁顺序排列。CeRhGe化合物的磁结构为共线(C模)，而NdRhGe化合物的磁结构由波矢k=(1 2，0，1 2)描述。分别位于Ce离子和Nd离子上的0.9(2)μ带和3.4(1)μ带的磁矩沿b轴排列。通过对称性分析证实了所确定的磁性结构。
Magnetic and structural properties of orthorhombic CeRhGe and NdRhGe (TiNiSi-type crystal structure) were studied by magnetometric and neutron diffraction methods. Both title compounds order antiferromagnetically below 10 K and 14 K respectively. The magnetic structure of the CeRhGe compound is collinear (C mode), whereas that of NdRhGe is described by the wavevector k = (1 2 ,0,1 2 ). Magnetic moments of 0.9(2) μBand 3.4(1) μBlocalized on Ce and Nd ions respectively, are aligned along the b-axis. The determined magnetic structures are confirmed by the symmetry analysis.
