在17 T磁场中对具有89° <$101 <$0 <$对称倾斜晶界的锌双晶进行了退火处理。边界迁移重新定向几乎垂直于表面。所观察到的效果是由于磁感应和毛细作用驱动的边界迁移的组合。测得的绝对边界迁移率约为2.5×10− 8 m4/Js。
Zinc bicrystals with 89° 〈101 ̄ 0〉 symmetric tilt boundary inclined at different angles to the free surfaces are annealed in the field of 17 T. Boundaries migrate reorienting almost perpendicular to the surfaces. The observed effect is due to combination of magnetically induced and capillarity driven boundary migration. The absolute boundary mobility was measured to be about 2.5×10−8m4/Js.
