摘要：

The linear thermal expansion of polycrystalline CeRhSb has been measured in the temperature range 77 K < T < 300 K under hydrostatic pressure up to 2.3 GPa. It is found that the thermal expansion coefficient alpha(T) at ambient pressure shows a maximum around T-max = 140 K and T-max increases with increasing pressure having rate of partial derivative T-max/partial derivative P = + 38.5 K/GPa. This fact shows that the Kondo temperature T-K is increased by applying pressure.
