Abstract
Ultrasonic attenuation measurements on a polycrystalline specimen of ErRh4B4 near 1° K and in magnetic fields up to 14 kOe are reported. A broad peak in zero-field attenuation is observed near Tc2, the temperature at which ferromagnetic order appears. At large magnetic fields ( > Hc2) a larger attenuation is observed when the propagation vector of the sound wave is perpendicular to the field direction than when it is parallel. The interpretation of these results is discussed.
