Giant Magnetostriction

The effect of annealing temperature on the magnetic and giant magnetostriction (GMS) of [ Fe / Tb / Fe / Dy ]n multilayer films were investigated. X-ray diffraction showed that the multilayer films' microstructures were still in amorphous at annealing temperature 300°C. The multilayer films began to crystalline at annealing temperature 400°C. The saturation magnetization of multilayer films increased by the increasing annealed temperature. The coercivity first decreased at annealing temperature 300°C and then increased when the annealing temperature was higher than 400°C. The multilayer films had good low-field GMS, and the magnetostriction of the multilayer films increased by the increasing annealing temperature.

Novel Applications

Abstract Recently giant magnetostriction materials have drawn a lot of attention because of their unique features which other materials, such as PZT, cannot provide. The features include outstanding magnetostriction, high energy density, high Curie temperature, and quick response. This paper presents two kinds of novel applications of giant magnetostriction materials: a compact fine positioner and a wire clamper. The former is able to achieve highly accurate positioning due to a novel structure design which substantially reduces the influence of Joule heat generated by the solenoid coil. The latter application is motivated by a great demand towards a wire-clamping device for semiconductor manufacturing, which is capable of maintaining a sufficient clamping force without fatigue.

Giant Magnetostriction

Abstract Magnetostriction is the emergence of a mechanical deformation induced by an external magnetic field. The conversion of magnetic energy into mechanical energy via magnetostriction at the nanoscale is the basis of many electromechanical systems such as sensors, transducers, actuators, and energy harvesters. However, cryogenic temperatures and large magnetic fields are often required to drive the magnetostriction in such systems, rendering this approach energetically inefficient and impractical for room-temperature device applications. Here, we report the experimental observation of giant magnetostriction in single-crystal nickel nanowires at room temperature. We determined the average values of the magnetostrictive constants of a Ni nanowire from the shifts of the measured diffraction patterns using the 002 and 111 Bragg reflections. At an applied magnetic field of 600 Oe, the magnetostrictive constants have values of λ100 = −0.161% and λ111 = −0.067%, two orders of magnitude larger than those in bulk nickel. Using Bragg coherent diffraction imaging (BCDI), we obtained the three-dimensional strain distribution inside the Ni nanowire, revealing nucleation of local strain fields at two different values of the external magnetic field. Our analysis indicates that the enhancement of the magnetostriction coefficients is mainly due to the increases in the shape, surface-induced, and stress-induced anisotropies, which facilitate magnetization along the nanowire axis and increase the total magnetoelastic energy of the system.
