  URh_2Ge_2 occupies an extraordinary position among the heavy-electron
122-compounds, by exhibiting a previously unidentified form of magnetic
correlations at low temperatures, instead of the usual antiferromagnetism. Here
we present new results of ac and dc susceptibilities, specific heat and neutron
diffraction on single-crystalline as-grown URh_2Ge_2. These data clearly
indicate that crystallographic disorder on a local scale produces spin glass
behavior in the sample. We therefore conclude that URh_2Ge_2 is a 3D
Ising-like, random-bond, heavy-fermion spin glass.
