摘要：

We have studied the Pr nuclear Schottky contribution to the specific heat of heavy fermion PrFe(4)Pi(12) in applied fields below 1 K using a high-quality single crystal. The results clearly show that the primary order parameter in the low-field ordered state is nonmagnetic. A possible explanation for the nature of the ordered state is discussed.
