Near-zero magnetostriction in magnetostrictive FeCo alloys
Scripta Materialia, 2021Abstract Soft magnetic metallic materials are the key components in generators, motors and transformers. The Curie temperatures of currently used soft magnetic metallic materials limit their applications in high-temperature environments.

Magnetostrictive microelectromechanical loudspeaker
The Journal of the Acoustical Society of America, 2013A microelectromechnical-loudspeaker based on the magnetostrictive effect is presented. The membrane consists of a comb structure of monomorph bending cantilevers with an area of about 16 mm2. Prototypes generate a sound pressure level (SPL) of up to 102 dB at 450 Hz with a total harmonic distortion of 2% inside a 2 cm3 measurement volume.

Effective magnetostriction of magnetostrictive composites
Applied Physics Letters, 1998An analytical method is developed for the effective magnetostriction of magnetostrictive composites based on Green’s function technique. For an elastically isotropic composite of magnetostrictive and nonmagnetostrictive phases, the analytical results give explicit effective-medium approximate formulas for the effective magnetostriction that fit well ...

Nature, 2015
All magnets elongate and contract anisotropically when placed in a magnetic field, an effect referred to as Joule magnetostriction. The hallmark of Joulian magnetostriction is volume conservation, which is a broader definition applicable to self-accommodation of ferromagnetic, ferroelectric or ferroelastic domains in all functional materials.

Abstract Magnetostriction is the phenomenon whereby the shape of a ferromagnetic specimen changes during the process of magnetization. The deformationδl/ldue to magnetostriction is usually very small, in the range 10−5 to 10−6 A deformation of this magnitude can be conveniently measured by means of a strain-gauge technique, the ...

Magnetostriction and magnetostrictive materials for sensing applications
Journal of Magnetism and Magnetic Materials, 2007In this paper, after an introduction to the basics of magnetostriction and magnetostrictive materials, some of their uses and applications are presented. New position sensors based on the magnetostriction effect and the magnetostrictive delay-line technique are presented with respect to their applicability in engineering systems.

Magnetostriction and Magnetoelasticity
2021The physical concepts magnetostriction and magnetoelasticity are presented. Spontaneous volume magnetostriction and saturation linear magnetostriction are distinguished. Various magnetoelastic phenomena are introduced, but the emphasis is on magnetostriction in bulk samples and thin films.

The article deals with sensors that exploit magnetostrictive materials. The contribution has mainly a tutorial form aiming to provide a self consistent description of the issue, from a macro-scale point of view, by presenting the magnetostriction effect, along with materials that naturally show a feeble effect, or special artificial alloys or compounds,

Journal of Applied Physics, 1968
This paper reviews work since 1961 on magnetostriction, including both its sources and its temperature and magnetic field dependence beyond saturation (forced magnetostriction). A statistical theory of the magnetostriction of ferromagnets is in fine agreement with experiments on nickel and on heavy rare-earth metals, which are reviewed in detail.
