Dependence of the noise of an orthogonal fluxgate on the composition of its amorphous wire-core
AIP Advances, 2020 In this paper we study the effect of magnetostriction of Co-rich amorphous microwire to the noise of the orthogonal fluxgates based on such wires. The magnetostriction was modified by changing the relative amount of iron x with the respect of the total ...

New elements within finite element modeling of magnetostriction phenomenon in BLDC motor
Open Physics, 2020 Reluctance forces are the main cause of vibration in electrical machines. The influence of magnetostriction is still the matter of controversy. In the article, program Ansys (typical for finite element method) was used to analyze stator deformation due ...

Magnetomechanical performance of directionally solidified Fe-Ga alloys [PDF]
, 2007 Iron-gallium alloys can produce magnetostrictions of ~400 ppm and might serve as mechanically robust actuator/sensing materials. However, for polycrystalline Fe-Ga alloys, the magnetostrictive performance decreases with the increasing deviations from the

Multiscale modeling of a low magnetostrictive Fe-27wt%Co-0.5wt%Cr alloy
AIP Advances, 2018 The present paper deals with the improvement of a multi-scale approach describing the magneto-mechanical coupling of Fe-27wt%Co-0.5wt%Cr alloy. The magnetostriction behavior is demonstrated as very different (low magnetostriction vs.

Universal signatures of the metamagnetic quantum critical endpoint: Application to CeRu2Si2 [PDF]
, 2010 A quantum critical endpoint related to a metamagnetic transition causes distinct signatures in the thermodynamic quantities of a compound. We argue that, irrespective of the microscopic details of the considered material, the diverging differential ...

MAGNETOSTRICTION OF GIANT MAGNETOSTRICTIVE THIN FILMS
Journal of Advanced Science, 1993 Magnetostriction of differently prepared TbFe2 and (Tb0.7Dy0.3) Fe2 thin films were measured using both a strain gauge and a beam bending method. Magnetostrictions up to 2⋅10-4 were found. Sputtered films showed a small hysteresis compared with ion plated films.

A universal platform for magnetostriction measurements in thin films
, 2015 We present a universal nanomechanical sensing platform for the investigation of magnetostriction in thin films. It is based on a doubly-clamped silicon nitride nanobeam resonator covered with a thin magnetostrictive film.
