Does magnetostriction cause energy loss?

The energy loss mechanism due to magnetostriction was clarified by analytical formulation considering the viscosity of magnetic materials. Effects of magnetostriction have been focused on contributions to magnetic anisotropy.

What does magnetostriction reveal?

The magnetostriction reveals the existence of a coupling between the elastic and magnetic properties of magnetic materials. The coupling is two-way and causes that, if a mechanical stress is applied to a magnetostrictive material, the magnetic configuration is concomitantly altered.

What is magnetostriction in engineering materials?

For engineering materials, magnetostriction is mainly concerned with the change in length (linear magnetostriction), which is the phenomenon of elongating or shortening along a certain direction driven by external magnetic field.

Does magnetostriction cause energy loss in soft magnetic materials?

Provided by the Springer Nature SharedIt content-sharing initiative The mechanism of energy loss due to magnetostriction in soft magnetic materials was analytically formulated, and our experiments validated this formulation.

How does magnetostriction affect magnetic energy dissipation?

When the domain wall in the magnetic material moves, the viscous resistance acts on the magnetic domain wall due to magnetostriction, and the viscosity of the magnetic material causes magnetic energy dissipation. We found that the energy loss due to magnetostriction increased with the frequency of the external magnetic field to power of 1.5.

Which materials experience magnetostriction?

All magnetically ordered materials experience magnetostriction. The materials relevant for applications are those in which the effect is either very large or nearly vanishing, together with those materials that combine a significant magnetostrictive effect with other interesting features as good mechanical properties.
