Abstract

In (100) oriented garnet films, the intrinsic crystalline anisotropy K is oriented so that there is an effective four-fold symmetry of anisotropy in-plane with K projections along the directions of the type <110>. Therefore, a contiguous disk pattern atop a (100) garnet film will more strongly hold bubbles in cusp positions when the centerline of disks is oriented along a <110> type direction than for the case of a <100> type direction.
