摘要：

The intermetallic compounds URhSi and URhGe have been studied by means of neutron powder diffraction. It was confirmed that the compounds crystallize in the orthorhombic TiNiSi-type structure with space group Pnma. The refined lattice and atomic positional parameters are presented. At 9.5 and 9.0 K, URhSi and URhGe undergo a magnetic phase transition into a ferromagnetic structure. Magnetic structure of URhSi is collinear with uranium moments (mu(ord) = 0.50(2) mu(B) at 1.4 K) oriented parallel to the c-axis. Magnetic structure of URhGe is non-collinear. The spin configuration in this compound can be described by two magnetic components; predominantly a ferromagnetic component (mu(F) = 0.43(2) mu(B)) oriented parallel to the c-axis and minority antiferromagnetic component (mu(AF) = 0.26(2) mu(B)) aligned along the alpha-axis.
