摘要：

The magnetoresistance (MR) and magnetostriction (MS) have been measured at high pressure for heavy fermion materials CeInCu2 and CeAl3. It is found that the sign of MR of CeInCu2 at 4.2 K changes from negative to positive around 1 GPa, which indicates that the system enters a coherent state. MS of CeInCu2 and CeAl3 is affected strongly by an application of pressure. The decrease in magnetude of MS is explained well by assuming the large enhancement of Kondo temperature T(K).
