Reversible Magnetic Field Induced Strain in Ni₂MnGa‐Polymer‐Composites

Composite materials consisting of magnetic shape memory alloy particles and a polymer matrix combine the advantages of both material classes: the high achievable magnetic field induced strain (MFIS) of 6% of Ni‐Mn‐Ga with a ductile matrix. Engineering the particle‐matrix interface as well as matching stiffness of polymer matrix is of importance for achieving high reversible MFIS to use this material as actuator or damper. We investigated those...
