In this study, we investigate the magnetic properties of interconnected permalloy nanowire networks using micromagnetic simulations. The effects of interconnectivity on the hysteresis curves, coercivity, and remanence of the nanowire networks are analyzed. Our results reveal intriguing characteristics of the hysteresis curves, including nonmonotonic behaviors of coercivity as a function of the position of horizontal nanowires relative to vertical nanowires. By introducing horizontal nanowires at specific positions, the coercivity of the nanowire networks can be enhanced without altering the material composition. The normalized remanence remains relatively constant regardless of the position of the horizontal wires, although it is lower in the interconnected nanowire arrays compared to nonconnected arrays. These findings provide valuable insights into the design and optimization of nanowire networks for applications requiring tailored magnetic properties.
在本研究中，我们使用微磁模拟研究了互连坡莫合金纳米线网络的磁性能。分析了互连性对纳米线网络的磁滞曲线、矫顽力和剩磁的影响。我们的结果揭示了磁滞曲线的有趣特征，包括矫顽力作为水平纳米线相对于垂直纳米线位置的函数的非单调行为。通过在特定位置引入水平纳米线，可以在不改变材料成分的情况下提高纳米线网络的矫顽力。归一化剩磁无论水平导线的位置如何都保持相对恒定，尽管与未连接的阵列相比，互连纳米线阵列中的归一化剩磁较低。这些发现为需要定制磁性能的纳米线网络的设计和优化提供了有价值的见解。
