Abstract
Effects of internal shear stress applied by torque on the magnetic properties of Fe-based amorphous alloys were studied under weak magnetic fields of less than 800 A/m, where strips were helically bonded onto the shaft so as to form an angle of 45° with respect to the thrust direction. It was found that the permeability of each amorphous alloy in different gluing conditions reached for each sample a constant value above a certain torque and these torque values depend on the internal compressive strain applied by gluing A magnetization process model is considered to explain the above-mentioned behavior and states that the compressive stress affects the restraint of magnetic domain wall displacement.Keywords
