摘要: 研究了直流电流退火的Fe73.5Cu1Nb3Si13.5B9合金薄带的巨磁阻抗效应，实验发现，经0.72 A电流退火10 min后，样品巨磁阻抗比有最大值1810.4%。经0.74 A电流退火10 min后，样品由于自身存在偏置场，其巨磁阻抗效应开始出现零磁场的非对称现象，结合XRD图谱分析表明，样品非对称巨磁阻抗效应的产生与B6-Fe23硬磁相的析出有关。 We have investigated the giant magneto-impedance effect ofFe73.5Cu1Nb3Si13.5B9 alloy ribbons which were annealed by DC current. It was found that the maximum GMI ratio was 1810.43% after 10-min annealing current of 0.72 A. However, the GMI effect began to show asymmetric phenomenon around zero magnetic field after 10-min annealing current of 0.74 A in terms of its own existence bias field. XRD spectrum analysis indicated that the B6-Fe23 hard magnetic phase precipitated should be responsible for the asymmetric giant magneto-impedance effect.
