Creep induced magnetic anisotropy in correlation with {Delta}E effect was investigated in the ribbons of the Fe{sub 74.7}Nb{sub 3}Si{sub 12.8}B{sub 9.5} amorphous alloy upon annealing treatment. It was found that hard-ribbon-axis anisotropy developed in the alloy due to the annealing under tensile stress of 207 MPa in the temperature interval 543 K--633 K. The maximum values of the magnetoelastic coupling coefficient 0.35 and 0.29 were obtained at the annealing temperatures 543 K and 633 K, respectively. Model calculations suggested that the domain structure and piezomagnetic properties are strongly influenced by the internal stress level.
