Fig. 4: Coupled stimulation for strip structures.

a Impact of different magnetization profiles and solvents on the deformation of strip structure. BM buckling instability-encoded magnetization. UM uniform magnetization. b Variation of phase shift with different magnetic field directions and stimuli types. c Simulation results for strip with buckling-encoded magnetization profile under the coupling stimulation of magnetic field and organic solvent. d Different buckling states of the strip induced by the coupled stimulation. e Deformation of strip structures under different stimulation sequences and magnetic field strength. B represents the applied magnetic field. The scale bars are 3 mm.
