  RRhGe (R=Tb, Dy, Er, Tm) compounds have been studied by a number of
experimental probes and theoretical ab initio calculations. These compounds
show very interesting magnetic and electrical properties. All the compounds are
antiferromagnetic with some of them showing spin-reorientation transition at
low temperatures. The magnetocaloric effect (MCE) estimated from magnetization
data shows very good value in all these compounds. The electrical resistivity
shows metallic behavior of these compounds. MR shows negative sign near
ordering temperatures and positive at low temperatures. The electronic
structure calculations accounting for electronic correlations in the 4f
rare-earth shell reveal the closeness of the antiferromagnetic ground state and
other types of magnetic orderings in the rare-earth sublattice.
