摘要：

We present an experimental study of the structural and magnetic properties of various polycrystalline samples of the new heavy-fermion antiferromagnet CePd2Al3, T(N) = 2.7 K. The relevant energy scales of the Kondo effect and crystal-field splitting are determined by comparing them with nonmagnetic LaPd2Al3. The critical dependence of the magnetic properties of rare-earth heavy-fermions on sample preparation is discussed using Doniach's Kondo lattice model.
