摘要: We observed a strong softening of longitudinal acoustic modes in UPt/sub 3/ and CeRu/sub 2/Si/sub 2/ high magnetic fields where the susceptibility exhibits an anomaly. The two phenomena can be correlated with large electronic Grueneisen parameter. Some shear exhibit oscillations same high-field low-temperature range.
