| Abstract: | The layered rare earth (RE) disilicides RE3Si5 with RE = Y, Er, Tm, YbandLu have been studied by means of ac magnetic susceptibility and ac electrical resistance measurements. Evidence for magnetic orderings have been found at 4.4K, 3.1K and 1.7K for Er3Si5 and at 2.1K for Tm3Si5. The resistance of Lu3Si5 was observed to drop abruptly below 7K, possibly indicating the presence of a superconducting phase. An apparent correlation was noted between the value of the room temperature resistivity and the amount of negative curvature observed in the resistivity above ～ 50K in these materials. |
