Magneto-acoustic properties of UCuGe single crystal

Original language description

Field and temperature dependence of sound-velocity and sound-attenuation were studied on a single crystal of the antiferromagnetic UCuGe (TN = 48 K). The temperature dependences of the sound velocity and attenuation display a pronounced anomaly at TN, which is evidence for a strong magneto-elastic interaction. The pulse-field measurements at 4.2 K show a minimum in the sound velocity followed by a jump-like anomaly at 37 T, and another kink-like anomaly at 48?49 T. These anomalies are due to field-induced spin rearrangements as measured in magnetization studies. In the paramagnetic state, both acoustic characteristics show large frequency-dependent changes revealing the presence of an unusual relaxation mechanism which might be due to vacancy dynamics.
