We report on studies on the magnetic and magnetoacoustic properties of uranium intermetallic antiferromagnets UCo2Si2, UCu0.95Ge, UIrGe and U2Ni2Sn in pulsed magnetic fields up to 60 T where they undergo metamagnetic transitions. The measurements were performed in the temperature range from 1.4 to 100 K. The magnetic ordering and the metamagnetic transitions are accompanied by pronounced anomalies in the ultrasound velocity and the ultrasound attenuation. All studies were performed on single crystals grown by the Czochralski method in a tri-arc furnace.
