Control over magnetic domains and domain walls is crucial for developing magnetic systems and devices. Here, we use a simple technique that uses a self-assembled reversible geometrical transformation from a flat 2D state to a rolled-up 3D state and back to the 2D state to create periodic up-down magnetization patterns in TbFe by applying a homogeneous magnetic field in the 3D state. We present how the magnetization patterns can be deterministically tailored simply by selecting the magnitude and direction of the applied magnetic field in the 3D state, which would otherwise require much more elaborate processes. This approach further provides a unique pathway to access and visualize magnetization processes in 3D by investigating the imprinted domains in the unrolled state of material magnetized at various fields in the 3D state. We further show that the overall 3D magnetization evolution can be reconstructed from recoil measurements in the 2D state when combined with the intrinsic anisotropy of the material. Finally, we discuss how this platform can be extended to investigate anisotropy changes in magnetostrictive materials, opening new possibilities for studying and engineering 3D magnetic states through reversible shape transformation.
