Abstract
Measurements of the saturation magnetostriction constant λs have been difficult for amorphous wires using conventional techniques due to their very thin form (125-10μm diameter). In this paper, magnetostriction measurements for these wires are stably carried out using a magnetization rotation model and applying a compressive stress to positive magnetostriction wires and a tensile stress to negative magnetostriction wires. The value of λs of 35 ppm was obtained for an as-prepared Fe77.5Si7.5B15 wire at room temperature.
