Abstract

Arrays of ordered segmented nanowires, which are ferromagnetic regions separated by non-magnetic inserts, are considered as a promising material for three-dimensional information storage systems. However, the presence of a large number of competing interactions significantly complicates the description of the magnetic behavior of such systems. In this paper, the effect of the segment length on the integral magnetic properties of Ni/Cu wires arrays is investigated. It is shown that the coercivity increases with an increase in the length of the magnetic segment for both the longitudinal and transverse directions of the long axis of the wires relative to the external magnetic field. A change in the direction of the easy magnetization axis was found with the ratio of the Ni segment length to the diameter in the range from 10 to 15.

随着Ni段长度的增加，分段Ni/Cu纳米线阵列易磁化轴方向的变化

摘要

有序分段纳米线阵列是由非磁性插入物分隔的铁磁区域，被认为是用于三维信息存储系统的有前途的材料。然而，大量竞争相互作用的存在使对此类系统磁行为的描述变得复杂。本文研究了段长对Ni/Cu线阵列整体磁性能的影响。结果表明，相对于外部磁场，在导线长轴的纵向和横向上，矫顽力随着磁性段长度的增加而增加。发现易磁化轴的方向随着 Ni 段长度与直径的比率在 10 到 15 的范围内发生变化。
