Passivity of Magnetostrictive Materials [PDF]
SIAM Journal on Applied Mathematics, 2007 Magnetostrictive materials display large force and displacement in response to an applied field, as well as short response time. However, their nonlinear and hysteretic behavior has hindered their use. We prove, using the physics of the material, that these materials are passive.

Unveiling hidden multipolar orders with magnetostriction [PDF]
Nature Communications, 2018 Broken symmetries in solids involving higher order multipolar degrees of freedom are historically referred to as “hidden orders” due to the formidable task of detecting them with conventional probes.

Advanced Science, EarlyView.This study achieves anisotropic thermal expansion tuning in Nd2(Co1‐xFex)17‐yCry compounds via a magnetoelastic strategy. Variable‐temperature synchrotron X‐ray diffraction reveals that increased Fe content induces switchable lattice responses. Compositional control reduces the volume expansion coefficient αV by 20% (x═0.7) and modulates TC (442–625 K),

Correlation between linear magnetostriction and magnetocaloric effect in the Fe7Se8 single crystals
Materials Research Express, 2022 The effect of the change in size under the influence of an applied magnetic field (magnetostriction) was studied in Fe _7 Se _8 single crystals. It was shown that a systematic change in the unit-cell constants, induced by an external magnetic field and ...
