我们报道了prru4p12单晶中的霍尔效应和磁电阻，该单晶在TMI=60 K时表现出金属-绝缘体（M-I）跃迁。霍尔系数在tmi上的温度依赖性异常表明费米表面发生了变化，而霍尔电阻率的非线性场依赖性和低温下电阻率的剧烈场抑制表明该化合物存在奇异基态。
We report Hall effect and magnetoresistance in a single crystal of PrRu4P12which was reported to exhibit a metal–insulator (M–I) transition at TMI=60 K . An anomaly in the temperature dependence of Hall coefficient across TMIindicates a change of Fermi surface, while non-linear field dependence of Hall resistivity and drastic field suppression of resistivity at low temperatures indicate an exotic ground state in this compound.
