摘要：

The attenuation of longitudinal and shear ultrasonic waves exhibits a peak at the spin-flop transition of Cr2O3. This peak is attributed to the presence of antiferromagnetic domains near the transition. The attenuation peak for longitudinal waves is accompanied by a dip in the phase velocity. The temperature variation of the spin-flop-transition field Hsf was measured from 4.2 to 305°K and is in very good agreement with earlier differential magnetization data obtained by Foner and Hou. At 4.2°K, Hsf=60.3±1.0 kG, whereas at 305°K, Hsf=121.2±1.5 kG. © 1969 The American Physical Society.
