Thermal expansion of CeRhSb under high pressure
Abstract
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 α(T) at ambient pressure shows a maximum around Tmax = 140 K and Tmax increases with increasing pressure having rate of ∂Tmax/∂P = + 38.5 K/GPa. This fact shows that the Kondo temperature TK is increased by applying pressure.
