Abstract
A magnetostrictive composite material exhibiting the capacity for large magnetostrictive strains was created by suspending magnetic wires in a soft polymer matrix. Magnetostrictive strains as large as 20% were found in an applied field of 600 Oe for this proof of concept composite. Our analysis indicates that reversible strains of over 6% are reasonable for this specific composite. The large values of magnetostriction are due to the mechanical rotation of the wires in the polymer matrix.
