We report the study of magnetism in a series of compounds of the type R{sub 5}T{sub 4}Sn{sub 10} (R=Ce, Pr, and Nd; T=Rh and Ir) at low temperatures. Magnetization, resistivity, and heat-capacity studies show that the three compounds of the series R{sub 5}Rh{sub 4}Sn{sub 10} undergo magnetic ordering below 10 K. The transition temperatures are 4.4, 5.5, and 7 K for Ce, Pr, and Nd compounds, respectively. There is a sharp anomaly in the heat-capacity and resistivity data of Nd{sub 5}Rh{sub 4}Sn{sub 10} below 6.5 K which we attribute to a first-order magnetic transition. However, susceptibility, resistivity, and heat-capacity studies show that although Ce{sub 5}Ir{sub 4}Sn{sub 10} orders antiferromagnetically below 4.2 K, Pr{sub 5}Ir{sub 4}Sn{sub 10} remains paramagnetic down to 1.5 K. La{sub 5}Ir{sub 4}Sn{sub 10} shows temperature-independent Pauli paramagnetism and does not exhibit superconductivity down to 1.5 K. The results are compared with that of R{sub 5}Ir{sub 4}Si{sub 10} series. {copyright} {ital 1997} {ital The American Physical Society}
