Abstract:
We report on magnetic-field-induced actuation of Ni50Mn28.5Ga21.5 single crystalline micropillars. Focused ion beam (FIB) milling technology was used to machine 45x45x120 micrometer3 cuboid pillars. The removal of about 2 µm of ion-beam-damaged surface layer enabled magnetic field actuation in pillars. Our results demonstrate the feasibility of manufacturing of microns-sized magnetic shape memory actuators by using Xe plasma source FIB technique.
