摘要：

The Kondo lattice compound CePd2Al3 appears to lie on the borderline between magnetic and nonmagnetic behavior. This has recently been concluded from the fact that the long range magnetic ordering is very sensitive to the metallurgical state of the sample. Single crystals of CePd2Al3 exhibit no magnetic order down to 0.3 K, while various polycrystalline samples are antiferromagnetic at T(N) = 2.7 K. Here, we present results of specific heat measurements on polycrystalline material under high pressure. Surprisingly, a weak initial increase of T(N) approximately 20 mK/kbar with pressure is observed, which is rather exceptional in Kondo lattice systems.
