Nanoindentation experiments are used to fabricate in a controlled manner arrays of micrometer and sub‐micrometer magnetic structures at the surface of nonmagnetic, atomically ordered, intermetallic sheets with composition Fe–40 % Al (at %). The figure shows atomic (top) and magnetic (bottom) force microscopy images of these fabricated structures. The ferromagnetism arises from the deformation‐induced atomic disorder in the intermetallic material.
