Thermal analysis lower saturation temperature

Fig. 29. GrUneisen analysis for CeAl3 showing the measured coefficients of specific heat (upper plot), thermal expansion (middle plot) and the Griineisen parameter deduced from their ratio (lower plot). As the temperature is lowered Q approaches saturation to a value 50. Below 1 K it Crosses over to a large negative value (-200) appropriate to the ground state. Data for C(T) from Phillips et al. (1987) for p from Andres et al. (1975) and from Ribault et al. (1979).
