Abstract
We report the discovery of a new type of non-Fermi liquid in CexLa1−xCu5.62Au0.38. When the Ce concentration x is decreased, the system changes into a dilute Kondo system. Its low-temperature susceptibility for \(x \lesssim 0.05\) is not described as a local Fermi liquid but characterized by a divergent behavior, 1/χ ∝ Tζ with the unusual exponent ζ ∼ 0.67. Correspondingly, the magnetization M exhibits an anomalous scaling behavior; (M/H)Hζ is a universal function of T/H (where H is magnetic field). We discuss the possible origin of this quantum-criticality-like behavior of the dilute system together with unusual temperature dependences of the heat capacity and electrical resistivity.
