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.

Magnetostriction of Electrical Steel and Its Relation to the No-Load Noise of Power Transformers
IEEE transactions on industry applications, 2018This paper analyzes the relationship between the experimentally determined magnetostriction of grain-oriented electrical steel (GOES) coils and the no-load noise of power transformers (PT).

Magnetostriction of a granular superconductor
Physical Review B, 1993An exactly solvable model for the magnetostriction (MS) of a granular superconductor is presented. Both the bulk-modulus-driven magnetostriction'' (the change of the sample's volume in the magnetic free energy upon the applied stress) and the change-of-phase magnetostriction'' (due to the stress dependence of the weak-links-induced magnetization) are ...

Magnetostriction Measurement By Interferometry
[1993] Digests of International Magnetics Conference, 1993A laser Doppler interferometric method using synchronous detection to measure the magnetostriction of soft magnetic films is described. The instrument measures 2 AA magnetostrictive deflections of Permalloy films on 500 mu m silicon substrates. Saturation magnetostriction of 10/sup -9/ can be measured for 1000 nm films on 100 mu m Si substrates.

Permeability dependence of the effective magnetostriction of magnetostrictive composites
Journal of Applied Physics, 2004A model is presented in this article to investigate the dependence of effective magnetostriction of the magnetostrictive composites on the parameters of components including the elastic modulus, permeability, and volume fraction, etc. Concentrating on the two-component magnetostrictive composites and choosing the two components to be general ...

AIP Conference Proceedings, 2002
Elastic waves are generated in a ferromagnetic material in a static magnetic field by a time-varying magnetic field which magnetostrictively couples to the material. We present modeling showing that this coupling is proportional not to the magnetostriction, but to the magnetization derivative of the static magnetostriction.

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.

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.

Minor rare earth Tb addition greatly enhances the magnetostriction of Fe 83 Ga 17 alloy. However, the structural origin of the enhanced magnetostriction remains unclear, since it is quite difficult to detect Tb element directly.
