Results on the static magnetic susceptibility and dc electrical resistivity of {ital R}{sub 5}Ir{sub 4}Si{sub 10} ({ital R}=Dy--Yb) compounds are presented. In addition, measurements of the ac magnetic susceptibility and resistivity at high pressure and heat capacity for Tm{sub 5}Ir{sub 4}Si{sub 10} are also reported. Magnetic-ordering temperatures for these isostructural compounds range from 0.8 to 5 K, with Tm{sub 5}Ir{sub 4}Si{sub 10} displaying two magnetic transitions. All these compounds exhibit an anomalous temperature dependence of the resistivity which may be attributed to charge-density-wave formation.
