Description
  • Magnetic and magneto-acoustic characteristics of UCu0.95Ge with antiferromagnetic ground state have been studied on single crystals in pulsed magnetic fields up to 64 T applied along the main axes. Along the a axis, a first-order phase transition has been observed at 61 T. For the field applied along the c axis, the first-order phase transition occurs at a much lower magnetic field (38 T). In both directions, the magnetization trends to saturate at 1.35 B per formula unit. These field-induced transitions as well as the spontaneous transition at the magnetic ordering at TN = 48 K are accompanied by pronounced anomalies in the sound velocity and sound attenuation. The field-temperature phase diagrams are constructed for both directions of the magnetic field. The results of our theoretical analysis within the framework of the mean-field approximation qualitatively agree with the observed behavior of magnetic and magneto-acoustic characteristics of UCu0.95Ge.
