## Abstract The off‐stoichiometric Ni~2~MnGa Heusler alloy is a magnetic shape‐memory alloy capable of reversible magnetic‐field‐induced strains (MFIS). These are generated by twin boundaries moving under the influence of an internal stress produced by a magnetic field through the magnetocrystallin
