摘要
Creep induced magnetic anisotropy in correlation with DELTAE effect was investigated in the ribbons of the Fe74.7Nb3Si12.8B9.5 amorphous alloy upon annealing treatment. It was found that hard-ribbon-axis anisotropy developed in the alloy due to the annealing under tensile stress or 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, repectively. Model calculations suggested that the domain structure and piezomagnetic properties are strongly influenced by the internal stress level.
