Abstract��The measurement of the magnetostriction of amorphous wires by the small angle magnetization rotation (SAMR) method was investigated. The dependence of the voltage of second harmonic wave on bias magnet and applied tensile stress and driving current was measured.Under optimal measurement condition, the saturated magnetostriction coefficient, ���˪���S, of Co����69.9��Fe��5Si����12.5��B��9Cr����3.5��Mo����0.1�� amorphous wire was measured, and the ���˪���S of 1��10����-7�� was obtained.
