摘要：

Measurements of the elastic constants in the normal and superconducting state on a high quality URu2Si2 single crystal exhibit large anomalies in the c11 mode versus temperature around 30 K and T(c). No such anomalies are visible in the c33 mode and in the shear elastic constants. We describe this behaviour with the anisotropic Gruneisen parameter coupling. Using the c11 anomaly a B-T phase diagram is determined which clearly shows the single phase bulk properties of superconducting URU2Si2. The magnetic field dependences of the shear waves in the superconducting and normal state can be interpreted quantitatively with a Lorentz force mechanism.
