  Abstract:  The fabrication of highly efficient integrated magnetostrictive sensors, actuators and transducers requires the availability of 3D-shaped magnetoelastic materials with high magnetostriction in low saturating fields. Up to now, Terfenol-D is the most used magnetostrictive material for magnetostrictive actuators and transducers, whereas magnetostrictive metallic glasses are preferred for sensors applications. Very recently, 2 new alternatives appeared: Fe-(Ga,Al) alloys, as single crystals or melt-spun ribbons, and Ni-Mn-Al and Co-based magnetic shape memory alloys (MSMs).
