The influence of stress/field annealing on magnetic domain structure and he
ld dependence of Young modulus (Delta E-effect) of amorphous Fe80Cr2B14Si4
ribbons was studied. The change of induced magnetic anisotropy is well refl
ected in magnetomechanical behaviour. The steepest reduction of Delta E is
observed in the same region of the annealed stress sigma(a) where the chara
cter of the domain structure changes. The experimentally observed behaviour
is qualitatively well explained by the theoretical model developed under t
he assumption that the stress/field-induced anisotropy is given by a superp
osition of the stress-induced and field-induced components. (C) 1999 Elsevi
