Decoupling Magnetoelastic and Magnetostatic Effects in Nanometric Films on Flexible Substrates Under In Situ Biaxial Multicracking (Adv. Funct. Mater. 40/2026)

Flexible Magnetic Systems The illustration highlights the strain-induced fragmentation of a magnetic thin film on a flexible substrate, leading to the formation of interacting mesoscale domains. It emphasizes how the resulting magnetic configuration emerges from the competition between magnetoelastic anisotropy and dipolar interactions, driven by the heterogeneous stress distribution within each fragment. The operando characterization combining X-ray diffraction and magneto-optical Kerr effect measurements is also depicted, providing a multiscale view of the magneto-mechanical coupling.
