The long-range dipole-dipole interaction in an array of Co57.3Fe7.6Cr1.7C33.4 amorphous microwires with axial bistability has been studied through magnetic hysteresis and longitudinally driven magneto-impedance (LDMI) measurements in this paper. Hysteresis loops performed for an array of microwires exhibit jumps and plateaux on the demagnetization curves. For LDMI curves, the multi-peak characteristic is presented as the number of microwires changes from 1 to 4. Each step in the hysteresis loops or each peak in the LDMI curves is correspondent to the magnetization reversal of an individual wire. To analysis the difference between the switching field of hysteresis loops and the peak field of LDMI curves, we further studied the dependence of the peak field on the driving current. The results showed that the ac magnetic field has a compensatory effect on the magnetization reversal of an individual wire.

通过磁滞和纵向驱动磁阻抗（LDMI）测量，研究了具有轴向双稳态的Co57.3Fe7.6Cr1.7C33.4非晶微线阵列中的长距离偶极-偶极相互作用。对微线阵列执行的磁滞回线在去磁曲线上表现出跳跃和平稳。对于LDMI曲线，当微导线的数量从1变为4时，将呈现多峰特性。磁滞回线中的每个步骤或LDMI曲线中的每个峰值都对应于单个导线的磁化反转。为了分析磁滞回路的开关场与LDMI曲线的峰值场之间的差异，我们进一步研究了峰值场对驱动电流的依赖性。
