Abstract
We present data for the temperature and magnetic-field dependence of the specific heat, magnetic susceptibility, magnetization, and electrical resistivity of U{sub 0.2}Y{sub 0.8}Pd{sub 3}. The data demonstrate the scaling behavior of the thermodynamic quantities at temperatures up to 10 K and magnetic fields up to 14 T. The magnetic field scales as {ital T}{sup 1.3}. The zero-field specific heat varies with temperature as {minus}{ital T} ln{ital T}. The magnetic field strongly affects the thermodynamics, but the magnetoresistance is very small ({minus}2% at {ital T}=0.36 K and {ital H}=14 T). We argue that our data are inconsistent with any single-impurity interpretation. We suggest that the system has a second-order phase transition at {ital T}=0.
