Abstract
Based on the random anisotropy model we calculate within the linearized theory of elasticity the volume averages (εij (r)) and (ε2ij (r)) of the total strain in magnetostrictively deformed amorphous and polycrystalline samples. The mechanism of magnetostriction is clarified, and effects of annealing or application of stress are discussed.
