Abstract

The ultrasonic properties of a URu₂Si₂ single crystal were measured in pulsed (25 ms) magnetic fields up to 50 T. In the frequency range from 20 to 200 MHz, both the attenuation and velocity of sound change markedly in the vicinity of the metamagnetic transitions (near 40 T). The data for URu₂Si₂ show three transitions, in agreement with earlier magnetization results of other authors. A unique fast data-acquisition ultrasonic spectrometer was assembled and utilized for these studies.
