Magnetostriction ‘‘jumps’’ in twinned Tb0.3Dy0.7Fe1.9
TL;DR: In this article, a model of twinned dendritic Terfenol-D was proposed, in which the magnetization of one twin jumps between two directions while the remaining twin undergoes a continuous rotation of the magnetisation.
Journal ArticleDOI
Magnetomechanical behaviour of rare earth iron-aluminium compounds
TL;DR: In this paper, the static differential permeability ( mu) and strain coefficient (d/sub 33/=d lambda /dH) of Terfenol-D were measured at room temperature.
Journal ArticleDOI
Actuation with Terfenol-D
TL;DR: In this article, the magnetomechanical properties of Terfenol have been determined by two independent experimental techniques, and the frequency response of the former is substantially different from theoretical predictions, casting doubt on the use of dynamic (AC) fields to measure the magnetostrictive strain coefficient.
Journal ArticleDOI
Control of Terfenol‐D under load
TL;DR: In this paper, a case study comparing the performance of two kinds of control strategy (both discrete), a conventional proportional and integral (PI) algorithm and a variable structure algorithm (DVSC) in both servo and cancellation/regulation roles was described.
Journal ArticleDOI
Magnetic and magnetoelastic response of stress cycled Terfenol-D
TL;DR: In this paper, the changes in magnetic and magnetomechanical properties of grain-oriented Terfenol-D have been monitored after stress cycling, showing that magnetic anisotropy is induced after ∼106 cycles of ±100 MPa about a mean preload of 120 MPa.
