- Abstract
One-way shape-memory effect (SME) controlled by temperature and magnetic field in rapidly melt-quenched (RMQ) Heusler-alloy (NiMnGa) ribbons is experimentally studied. Two-way SME that results from training is demonstrated for submicron NiMnGa samples. Reversible thermally and magnetically controlled bending of no less than 1.5% and deflection of no less than 2 μm are reached for composite NiMnGa/Pt microactuators with sizes of 25 × 2.3 × 1.7 μm in the presence of magnetic field of μ Н = 8 T at an initial temperature of 63°С.
