Static magnetic properties such as coercive force, hysteresis loss and magnetic flux density have been studied under various tensile stresses up to about 140 MPa for an amorphous Fe79.3Si9.2B11.1Al0.4 alloy.The tensile stress dependence of coercive force has been discussed by a simple model based on the domain wall motion proposed by Kondorski and Kersten. The dependence can be explained by assuming two compressive stresses σc1 and σc2 which exist in the bulk portion and surface layers, respectively. The values of σc1 and σc2 are estimated to be 1 MPa and 7 MPa, respectively.
