| Abstract: | Non-uniform spin states (stripe domains) are induced by powerful pulse ultrasonic waves in a hematite ( -Fe2O3) single crystal. These states are visualized with the help of the Cotton-Mouton effect and quantitatively described in terms of an effective field proportional to the square of ultrasound amplitude. |
| Keywords: | Easy plane antiferromagnet Ultrasound High intensity Spin reorientation Domains Effective field |
