• Rapid-solidified, melt-spun ferromagnetic shape memory Fe-29.6at%Pd alloy was fabricated to develop a new type of magnetostrictive material. The thin plate samples showed stronger crystal anisotropy and larger shape memory effect. Magnetostriction changed with increasing temperature up to 1750 microstrain at H=10kOe just below the inverse phase transformation temperature. This phenomenon might be caused by the magnetically induced re-arrangements of the activated martensitic twin variants. The basic mechanism of this giant magnetostriction and its dependency on metallurgical microstructures are discussed.
