a Before rolling, a rectangular membrane will prefer magnetization along the long axis (axial). After rolling, the domain configuration will change as a function of membrane width or closing angle φ from (b) axial to (c, d) azimuthal. In addition to the 3D view, a 2D sketch (black lines) illustrates the cross-sectional view of planar and curved membranes.
