We have measured the low-temperature electrical resistivity rho and thermal conductivity lambda of a selection of RERh/sub 4/B/sub 4/ compounds. The compound LuRh/sub 4/B/sub 4/ served as the standard material concerning superconductivity and HoRh/sub 4/B/sub 4/ as that for magnetic ordering. For ErRh/sub 4/B/sub 4/ we studied, in particular, the transition from the superconducting to the normal state with decreasing temperature. In SmRh/sub 4/B/sub 4/ both rho(T) and lambda(T) reveal the strong interaction between the magnetic moments of the Sm/sup 3 +/ ions and the conduction electrons, which is partly quenched at the transition to the antiferromagnetic state. Depending on the material considered, the thermal conductivity data are analyzed using theoretical calculations due to Bardeen, Rickayzen, and Tewordt; Kadanoff and Martin; and Ambegaokar and Griffin.
