    Magnetic and magnetoelastic properties of UCo2Si2 as studied by high-field magnetization and ultrasound measurements

  • Original language description

    We investigated antiferromagnet UCo2Si2 by magnetization and ultrasound measurements in pulsed magnetic fields up to 60 T. It is found that the crystal UCo2Si2, which has the AF type-I magnetic structure in zero field below TN=83 K, undergoes the metamagnetic phase transition to ferrimagnetic structure ++- type. The transition occurs when the magnetic field is applied along the c axis at 45 T (at 1.5 K). The transition is extremely sharp and exhibits a small but non-negligible hysteresis. With increasing temperature, it becomes broader and vanishes at TN. In ultrasound measurements, the transition appears as anomalies in the sound velocity and attenuation. Our analysis suggests that the low-temperature changes in the sound velocity and attenuation aredetermined by exchange renormalization caused by the sound waves.
