We present results of a magneto-acoustic study of UCu0.95Ge. This compound exhibits antiferromagnetic ordering at 48 K and shows a metamagnetic phase transition at 38 T for the magnetic field applied along the c direction, seen as a jump in themagnetization. The sound velocity and sound attenuation demonstrate pronounced anomalies in the vicinity of both magnetic phase transitions proving the important role of magnetoelastic interactions in the physics of this actinide compound.
