我们研究了非费米液体（NFL）化合物Ce（Ru0.5Rh0.5）2Si2的磁性和输运性质与温度和场的依赖关系。对于场H小于0.1T的情况，结果表明观察到的NFL行为是无序驱动的。然而，对于更高的领域，磁和运输性能的主导传导电子的耦合临界自旋波动。的磁化率的温度依赖性，以及磁电阻的标度特性是在最近的动态平均场理论的近藤合金接近自旋玻璃量子临界点的预测非常好的协议。
We study the temperature and field dependence of the magnetic and transport properties of the non-Fermi-liquid (NFL) compound Ce(Ru0.5Rh0.5)2Si2. For fields H less, similar0.1 T the results suggest that the observed NFL behavior is disorder driven. For higher fields, however, magnetic and transport properties are dominated by the coupling of the conduction electrons to critical spin fluctuations. The temperature dependence of the susceptibility as well as the scaling properties of the magnetoresistance are in very good agreement with the predictions of recent dynamical mean-field theories of Kondo alloys close to a spin-glass quantum critical point.
