Magnetostrictive properties of polymer bonded Terfenol-D

Abstract A resin bonding route has been used to produce rods of the highly magnetostrictive alloy Tb 0.27 Dy 0.73 Fe 1.93 . The influence of the resin load on the magnetic properties has been studied. Two phenomena could be observed during the measurement of the magnetomechanical factor. The first was a threshold value of applied magnetic field. The second was abnormal behaviour of the characteristic frequencies with applied bias field.
