ABSTRACT
The effect of constant tensile elastic stresses on the field dependence of the magnetoelasticity (Δ E effect) of Fe64Co21B15 amorphous ferromagnetic ribbons after thermomagnetic treatment in a temperature interval from 290 to 360°C has been studied. The maximum value of the negative Δ E effect increases upon application of a relatively small tensile stress and decreases under the action of large stresses. In addition, the application of tensile stresses decreases the magnetic field corresponding to a maximum negative Δ E effect. The results are explained based on notions about the influence of constant tensile stresses on the domain structure of ferromagnetic materials with positive magnetostriction and induced uniaxial anisotropy.
