Observational analysis reveals magnetically induced tensile stresses in NiMnGa composites, pointing to enhanced magnetostrain performance.
The magnetically induced stresses in “Fe/Ni–Mn–Ga single crystalline particles/Fe” laminate composites have been studied depending on the thickness of the framing Fe foils and the distances between them. It evaluated the magnetically induced repulsive force between the two Fe foils which results in additional tensile stress of NiMnGa particles experimentally observed before. The presented calculation shows the way to improve the magnetostrain performance of laminate composite actuators.
