Magnetostriction strain measurement: heterodyne laser interferometry versus strain gauge technique [PDF]

open access: yes, 2013
Deformation of the ferromagnetic material, known as magnetostriction, causes vibrations and noise of electrical machines and transformer cores. A setup by using heterodyne laser interferometers has been built to measure the magnetostriction strains as a

Giant magnetothermal conductivity and magnetostriction effect in charge ordered Nd$_{0.8}$Na$_{0.2}$MnO$_{3}$ compound

open access: yes, 2015
We present results on resistivity ($\rho$), magnetization ($M$), thermal conductivity ($\kappa$), magnetostriction ($\frac{\Delta L}{L(0)}$) and specific heat ($C_{p}$) of charge-orbital ordered antiferromagnetic Nd$_{0.8}$Na$_{0.2}$MnO$_{3}$ compound ...

Direct and inverse measurement of thin films magnetostriction

open access: yes, 2009
Two techniques of measurements of thin film magnetostriction are compared: direct, when changes of the substrate curvature caused by the film magnetization are controlled, and inverse ("indirect"), when the modification of the magnetic anisotropy induced

Ultrahigh‐Strength Soft‐Magnetic NiFeCoAl Multi‐Principal Element Alloys Enabled by Multiscale Heterostructure Design

open access: yesRare Metals, Volume 45, Issue 4, April 2026.
ABSTRACT Soft‐magnetic materials (SMMs) are indispensable for electrification and sustainable energy systems, yet their inherent mechanical fragility fundamentally limits applications under severe mechanical stresses. Enhancing the yield strength of SMMs is essential to prevent the degradation in magnetic performance and failure from plastic ...

"Cold Melting" of Invar Alloys

open access: yes, 2000
An anomalously strong volume magnetostriction in Invars may lead to a situation when at low temperatures the dislocation free energy becomes negative and a multiple generation of dislocations becomes possible.

Efficient Process Development for Laser Powder Bed Fusion of a Soft‐Magnetic Metallic Glass Composite

open access: yesAdvanced Engineering Materials, Volume 28, Issue 6, 18 March 2026.
Iron‐based metallic glass alloys exhibit excellent soft‐magnetic properties, and unprecedented geometrical freedom in the design of soft‐magnetic metallic glass components is made possible by additive manufacturing. An efficient workflow for developing parameters for laser‐based powder bed fusion of a Fe‐based metallic glass alloy is presented along ...

Measurement and analysis of magnetostriction of nanocrystalline alloy laminations under medium-frequency excitation

open access: yesAIP Advances
Nanocrystalline alloys, widely used as core materials of medium-frequency transformers, require accurate measurement of their magnetostriction to calculate the core vibration and noise during the transformer design phase.

Modelling of magnetostriction of transformer magnetic core for vibration analysis

open access: yesOpen Physics, 2017
Magnetostriction is a phenomenon occurring in transformer core in normal operation mode. Yet in time, it can cause the delamination of magnetic core resulting in higher level of vibrations that are measured on the surface of transformer tank during ...
