抄録

The electrical resistivity of single-crystalline CeAl₂ has been measured under high pressure up to 2 GPa in the temperature range 2-280 K. It is found that the magnetic contribution to the resistivity of CeAl₂ has two peaks at T₁ (=5 K) and T_m (=70 K) and these temperatures decrease with increasing pressure. The behavior of T_m at high pressure is attributed to the pressure dependence of the Kondo temperature and the splitting energy of 4f levels by the crystalline electric field. The Kondo state of CeAl₂ under high pressure is briefly discussed on the basis of thermodynamics.
