Pressure dependences of the specific heats of UPt3, UBe13 and CeAl3

Pressure dependences of the specific heats of UPt3, UBe13 and CeAl3

The specific heats of UPt3, UBe13 and CeAl3 have been measured under pressures to ≈9 kbar. The densities of electronic states decrease sharply with increasing pressure. For UPt3 the spin fluctuation terms decrease with increasing pressure, suggesting a positive correlation with superconductivity. Fo...

Zusammenfassung:The specific heats of UPt3, UBe13 and CeAl3 have been measured under pressures to ≈9 kbar. The densities of electronic states decrease sharply with increasing pressure. For UPt3 the spin fluctuation terms decrease with increasing pressure, suggesting a positive correlation with superconductivity. For CeAl3, there is a qualitative change in the temperature dependence of the specific heat.
