Abstract
We have investigated the transport, magnetic, and thermal properties of the ternary compounds R6Ni2Sn (R = Sc, Y, and Rare earth) by means of the electrical resistivity ρ(T), dc magnetic susceptibility (T) and specific heat C(T) measurements. Among the R6Ni2Sn, only R = La is found to become superconducting at 2.3 K. The electrical resistivity ρ(T) curves of R = Sc, Y, Ce and Pr exhibit typical characteristics of common metal and show no magnetic transitions above 8 K. R = Nd, Sm, Gd, Tb, Dy and Ho show some anomalies. Magnetic ordering are observed in R = Nd, Sm, Gd, Tb, Dy and Ho as revealed from theρ(T), C(T) and (T) curves. In addition, the C(T) curve of Ce6Ni2Sn shows the behavior of heavy fermion compounds.
