我们成功地生长了RRu2Al10（R = La和Pr）单晶，并测量了它们的电阻率和霍尔效应，从而更深入地了解了ceru2al10在0 ~ 27 K以下表现出不同寻常的长程序（LRO）。laru2al10和prru2al10的电阻率随温度的变化均表现出典型的金属行为，没有发生任何相变。霍尔效应测量表明，LRO区ceru2al10的载流子数比LaRu2Al10的载流子数少约30倍，表明这两种化合物在t0以下的电子态差异很大。
We have succeeded in growing single crystals of RRu2Al10(R = La and Pr), and measured their electrical resistivity and Hall effect to gain the deeper insight of the physical properties of CeRu2Al10which exhibits an unusual long-range order (LRO) belowT0∼27 K. The temperature dependences of the electrical resistivity of both LaRu2Al10and PrRu2Al10show the typical metallic behavior without any phase transition. The Hall effect measurements reveal that the carrier number of CeRu2Al10in the LRO region is about 30 times smaller than that of LaRu2Al10, indicating highly different electronic states between these compounds belowT0.
