摘要

Magnetic and mechanical properties of Co-rich amorphous ndcrowires of nominal compositions (Co_1-xMn_x)75Si_10B_15(0.08 < x < 0.l1) and Co_56Fe_6.5Ni_10B_16Si_11 with nearly zero magnetostriction constant have been studied. Drastic changes of the hysteresis loop with the decrease of x from rectangular to flat shape were observed at x < 0.l, while the Co_56.5Fe_6.5Ni_10B_16Si_11 microwire showed rectangular hysteresis loops. Compositions with x ≥ 0.l have small but positive magnetostriction constant while negative λ_s. values have been observed at x ≤ 0.09, indicating rectangular character of the hysteresis loop in samples with nearly zero and even for small negative λ_s' Extemal stress dependence of switching field, H*, showed an increase of H* with σ for samples with x = 0.11 and a decrease of H* with σ for x = 0.1. Besides, microwires of the same composition but with different dimensions showed different H*(σ) dependencies.
