Abstract
The results of specific heat and susceptibility measurements on PrNi2 over the temperature region from 12 mK to 80 K are reported. Anomalies in the susceptibility and the magnetic relaxation time are found at 0.25 K. The specific heat starts to increase around 0.5 K, much higher than 0.25 K, and it continues increasing at the lowest measured temperature of 30 mK. The entropy estimation shows that the specific heat anomaly below 1 K is predominantly nuclear in origin. Data are discussed in terms of a mixed nuclear-electronic transition at 0.25 K.
