Аннотация
Bimetallic composite nanotweezers based on Ti2NiCu alloy with shape memory effect (SME) have been recently proved to allow the manipulation of real nano-objects, such as nanotubes, and bionanoparticles while heated up to 40-60 °C by laser radiation. The possibility of developing nanotweezers operating at a 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 25×2.3×1.7 μm3. The controlled bending deformation of the actuator is 1.2 %, with a deflection of the end of the actuator higher than 2 μm has been 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.
