The magnetostriction of stress-induced Fe7Pd3 martensite has been investigated. The striction reaches a value 1980 ppm if this martensite is induced by a compressive stress of -12 MPa in the small temperature interval Ms≤T≤Ms+10°C. It is proposed that the observed magnetostriction reflects the formation and response of metastable adaptive orthorhombic martensite to the externally applied magnetic field.
