Phys. Rev. Lett. 86, 524–527 (2001)Non-Fermi-Liquid Scaling in Ce(Ru0.5Rh0.5)2Si2See Also: Erratum Received 23 February 2000; published in the issue dated 15 January 2001 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≲0.1 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. © 2001 The American Physical Society URL:
