摘要：

UCu5-xPdx alloys are heavy-fermion materials with indications of non-Fermi liquid (NFL) behavior for x = 1 and 1.5. We report on the specific heat C of UCu4Pd measured between 0.08 and 3.5 K which shows NFL behavior C/T similar to -ln(T/T0) down to 0.2 K but indicates spin-glass freezing around 0.2 K. This is confirmed by measurements of the DC magnetization and the AC susceptibility.
