Abstract

Magnetoresistance (MR), magnetoinductance (mi), and magnetoimpedance (MI) studies on the as-quenched and annealed Fe₇₂Si₁₀Cu₁Nb₂B₁₅, Co₇₂Ni₅Si₅Cu₁Nb₂B₁₅, and Co₇₇Si₅Cu₁Nb₂B₁₅ ribbons have been carried out in the present investigation. Structural studies indicate that all as-quenched samples are in the amorphous phase. The asymmetry in the MI, MR, and mi curves is noticed and is attributed to induced magnetocrystalline anisotropy and hysteretic magnetization. Among all three samples, the Co₇₇Si₅Cu₁Nb₂B₁₅ ribbons exhibit the highest magnetization and MI values. The development of a strong transverse magnetic anisotropy upon annealing has been observed in the Co₇₇Si₅Cu₁Nb₂B₁₅ ribbons, while such features are not observed in other cases. The present study shows that 5% Ni substitution in Co₇₇Si₅Cu₁Nb₂B₁₅ samples significantly reduces the transverse anisotropy, indicating that the transverse anisotropy can be tuned through Ni substitution.

调谐熔融纺丝带的磁阻、磁阻和磁感应强度

本研究对淬火和退火的 Fe72Si10Cu1Nb2B15、Co72Ni5Si5Cu1Nb2B15 和 Co77Si5Cu1Nb2B15 晶带进行了磁阻（MR）、磁感应强度（mi）和磁阻（MI）研究。结构研究表明，所有淬火样品都处于非晶相。注意到 MI、MR 和 mi 曲线的不对称性，这归因于诱导磁晶各向异性和滞后磁化。在所有三种样品中，Co77Si5Cu1Nb2B15 晶带的磁化率和 MI 值最高。Co77Si5Cu1Nb2B15 晶带在退火后出现了较强的横向磁各向异性，而在其他情况下则没有观察到这种特征。本研究表明，Co77Si5Cu1Nb2B15 样品中 5% 的镍替代能显著降低横向各向异性，这表明横向各向异性可通过镍替代进行调整。
