Abstract:
The heat capacity of CePd3B0.3 has been measured between 80 mK and 2.5 K in zero and applied fields up to 4 T. The specific heat exhibits a Schottky-like anomaly, nearly symmetric on a lnT scale, which is shifted to higher temperatures in applied fields. High-temperature susceptibility measurements confirm a near trivalent state of Ce in CePd3B0.3 while the ac susceptibility in the range 0.15 to 0.7 K displays a cusp at 0.45 K which is smeared out in applied fields indicating a spin-glass transition. Kondo interactions are also operative as evidenced by the large value of C/T as T→0.
