摘要：

Paper presents the results of magnetoelastic investigation carried out on the ribbon ring-shaped samples made of Fe81Si4B14 amorphous alloy. Samples were subjected to different thermal treatment in magnetic field to reduce value of residual stresses generated during the rapid quenching process as well as induce anisotropy. Under the influence of compressive stresses, the shape of hysteresis loop changes significantly for all investigated samples. The highest stress sensitivity was observed for sample annealed in the magnetic field perpendicular to the ribbon direction. In this case flux density B increased from 75 mT to 205 mT under compressive stress up to 10 MPa.
