Abstract

We have studied the high pressure effect on the antiferromagnetic ground states of uranium heavy fermion compounds. In this paper we show our high pressure studies on U2Zn17 by the electrical resistivity measurements. In U2Zn17, the Néel temperature TN in U2Zn17 decreases slightly from 9.66 K at 1 bar to 9.33 K at 2.5 GPa, becomes almost pressure-independent up to 4.7 GPa, and starts to increase at the higher pressure region. We discuss the pressure dependences of the coefficient of T2 term in the electrical resistivity A, an antiferromagnetic gap δ and a characteristic temperature Tρmax. It is found that the effect of pressure on the electronic states in U2Zn17 is weak compared with the other heavy fermion compounds. The experimental results on UCu5 is also discussed briefly.
