摘要
We present data for the temperature and magnetic-field dependences of the specific heat, magnetic susceptibility, magnetization, and electrical resistivity Of U0.2Y0.8Pd3. 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 T1.3. The zero-field specific heat varies with temperature as - T ln T. The magnetic field strongly affects the thermodynamics, but the magnetoresistance is very small (-2% at T = 0.36 K and 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 T = 0.
