Migration and reorientation of grain boundaries in Zn bicrystals during annealing in a high magnetic field

Zinc bicrystals with 89° 〈1 0 1 ̄ 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 dri...

Description
Summary:Zinc bicrystals with 89° 〈1 0 1 ̄ 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 −8 m 4/J s.
