| Popis: | Bimetallic composite nanotweezers based on Ti2NiCu alloy with shape memory effect (SME) have recently demonstrated the ability to manipulate real nano-objects, such as nanotubes, and bionanoparticles when heated to 40-60 C by laser radiation. The possibility of developing nanotweezers operating at constant temperature is of particular importance mainly for the manipulation of biological objects. In this work, a microactuator was produced using a composite bilayer made of a layer of rapidly quenched Ni53Mn24Ga23 ferromagnetic shape memory Heusler alloy and an elastic layer of Pt. The size of the microactuator is 25x2.3x1.7 micro-meters3. A controlled bending deformation of the actuator of 1.2 %, with a deflection of the end of the actuator higher than 2 micro-meter was obtained by applying a magnetic field of 8 T at T = 62 C. The possibility of the development of new technologies for magnetic-field-controlled nanotools operating at a constant temperature using the new multifunction magnetic shape memory alloys will be discussed.
