论文摘要
金属条形码纳米线（BNWS）由模板辅助电沉积制造的重复异质段组成，可以在磁，电气，机械和生物医学应用中提供扩展功能。我们可以将这种纳米结构视为具有磁相互作用的三维系统，其磁性行为与复杂的磁相互作用强烈影响。这项研究讨论了段的几何参数对其相互作用特征的影响以及具有交替磁化的BNW阵列的总体磁性行为。通过控制施加的电流密度和电沉积中的经过的时间，我们调节了Fe-Au BNW的尺寸。我们表明，FE和AU段是由具有高磁化强度和低磁化的FE-AU合金制成的。在微磁模拟的帮助下，我们发现并分析了BNW阵列中三种类型的磁相互作用。结果，我们证明了相互作用的主导类型取决于Fe和Au段的几何参数以及交叉和插图的距离。
Metallic barcode nanowires (BNWs) composed of repeating heterogeneous segments fabricated by template-assisted electrodeposition can offer extended functionality in magnetic, electrical, mechanical, and biomedical applications. We can consider such nanostructures as a three-dimensional system of magnetically interacting elements with magnetic behavior strongly affected by complex magnetostatic interactions. This study discusses the influence of geometrical parameters of segments on the character of their interactions and the overall magnetic behavior of the array of BNWs having alternating magnetization. By controlling the applied current densities and the elapsed time in the electrodeposition, we regulate the dimension of the Fe-Au BNWs. We show that the Fe and Au segments are made of Fe-Au alloys with high and low magnetization. With the help of micromagnetic simulations, we discover and analyze the three types of magnetostatic interactions in the BNW arrays. As a result, we demonstrate that the dominating type of interaction depends on the geometric parameters of the Fe and Au segments and the interwire and intrawire distances.
