Abstract
We observed a strong softening of longitudinal acoustic modes in and in high magnetic fields where the magnetic susceptibility exhibits an anomaly. The two phenomena can be correlated with a large electronic Grüneisen parameter. Some shear modes exhibit oscillations in the same high-field and low-temperature range.
